RELATED APPLICATIONS 
     This application is a claims the benefit of U.S. Provisional Application No. 62/173,120 filed on Jun. 9, 2015, the entire contents of which are incorporated herein by reference. 
    
    
     BACKGROUND 
     Physical measurements of human bodies are useful for various purposes. For instance, health professionals use physical measurements to calculate body mass index (BMI). BMI is a measurement of a person&#39;s body fat based on the person&#39;s height and weight that can be used to determine whether the person is underweight, overweight, obese, etc. BMI, waist measurement, etc. can be useful for determining whether persons are at risk for various diseases. Additionally, many apparel companies use physical measurements to determine sizes and fits of garments. Collecting physical measurements, however, is time consuming Additionally, persons can find themselves in situations where tools used for determining physical measurements are not accessible, such as in the developing world, in online applications, etc. 
     SUMMARY 
     This disclosure describes utilizing graphical elements representing human bodies to estimate physical measurements of a person. In at least one example, a service provider can access a database storing a plurality of data items. The service provider can cause a set of data items of the plurality of data items to be presented to the user. Data items in the set of data items are associated with at least one graphical element representing a human body with individual magnitudes corresponding to individual dimensions of a plurality of dimensions. The service provider can receive data indicating a selection of a data item associated with a first magnitude associated with a first dimension and a second magnitude associated with a second dimension. The service provider can estimate physical measurements associated with the user based partly on a first magnitude and/or the second magnitude.

     DETAILED DESCRIPTION 
     This disclosure describes utilizing graphical elements representing human bodies to estimate physical measurements of a person. Technologies described herein can enable physical measurements to be estimated without requiring access to measuring devices such as scales, measuring tapes, body fat meters, body fat calipers, etc. That is, the technologies described herein include estimating physical measurements when few or no measuring devices are available using data items associated with graphical elements representing human bodies and inputs associated with the data items. The technologies described herein can be used to replace, assist, and/or supplement technologies currently implemented to determine physical measurements using various measuring devices (e.g., scales, tape measures, etc.). 
     For illustrative purposes, a physical measurement represents a definite magnitude of a physical quantity that is used as a standard for quantifying a dimension of a part of the human body and/or a characteristic of the human body. Physical measurements can be associated with any system of units (e.g., metric system, United States customary measurement system, natural unit system, etc.). A physical measurement can be a definite magnitude of a physical quantity of dimension of a user&#39;s neck (e.g., circumference, length, width, etc.), upper arm (e.g., circumference, length, width, etc.), chest (e.g., circumference, length, width, etc.), bust (e.g. circumference, etc.), waist (e.g., circumference, length, width, etc.), hips (e.g., circumference, length, width, etc.), thigh (e.g., circumference, length, width, etc.), calf (e.g., circumference, length, width, etc.), leg (e.g., circumference, length, width, etc.), arm (e.g., circumference, length, width, etc.), etc. Physical measurements can include measurements of a user&#39;s height, weight, body fat percentage, etc. 
     Physical measurements can also include measurements that are determined based on other physical measurements, such as BMI, as described above. BMI is an estimate of a user&#39;s body fat based on the user&#39;s height and weight that can be used to determine whether a user is underweight, overweight, obese, etc. BMI can be useful for determining whether users are at risk for various diseases. BMI is determined based on dividing a user&#39;s mass in kilograms by the square of the user&#39;s height in meters, or by multiplying a user&#39;s mass in pounds by 703 and dividing the product by the square of the user&#39;s height in inches. 
     Technologies described herein cause one or more sets of data items to be presented to a user via an interface of a device that can be associated with the user (e.g. a user device). Each data item can be associated with at least one graphical element representing a human body having individual magnitudes of individual physical measurements corresponding to individual dimensions. That is, a data item can be associated with at least one graphical element that graphically represents a human body that has proportions that are consistent with a real human body having individual physical measurements corresponding to individual magnitudes. The graphical elements can be graphical representations of human bodies, such as two-dimensional or three-dimensional graphical representations of human bodies. 
     As described above, the technologies described herein can cause one or more sets of data items to be presented to a user via an interface of a device that can be associated with the user (e.g. a user device). A set of data items includes one or more data items. In at least one example, a set of data items can be a subset of data items from a database of data items. Individual data items in a set of data items can be associated with at least one graphical element representing a human body with magnitudes associated with physical measurements that are different from other individual data items in the set of data items. For instance, each of the data items in a set of data items can be associated with at least one graphical element representing a human body with magnitudes including a first magnitude associated with a first dimension and a second magnitude associated with a second dimension. In at least one example, the first magnitude can be the same for all data items in the set of data items and the second magnitude can be different for each data item in the set of data items. For instance, a set of data items can include data items associated with at least one graphical element that represents human bodies that have same BMIs and different waist measurements. In some examples, the magnitudes represented by graphical representations in each data item can differ from other data items in a set of data items by a single magnitude associated with a single dimension. That is, all of the magnitudes associated with all of the dimensions can be the same except for one magnitude associated with one dimension. For instance, a set of data items can include data items each associated with at least one graphical element that represents a human body that has all of the same magnitudes as the other data items in the set of data items except that each data item in the set of data items is associated with at least one graphical element that represents a human body with a different waist measurement. 
     The user can select a data item that is associated with graphical elements representing human bodies that look most like themselves, or in some examples, another person (e.g., a friend, a family member, a suspected criminal/person of interest, etc.), as described below. The service provider can receive data indicating the user selection. Based at least in part on receiving the data associated with the user selection, the service provider can retrieve second (or subsequent) sets of data items. In at least one example, at least one of the magnitudes represented by individual data items in the second (or any subsequent) set of data items can be based on the magnitudes represented by the data item selected by the user from the previous set of data items. As a non-limiting example, if the second set of the data items includes individual data items that are associated with one or more graphical elements representing human bodies that have different BMIs, the individual data items can be associated with one or more graphical elements representing human bodies with a same waist measurement based on the waist measurement corresponding to the data item selected by the user in the first set of data items. The technologies described herein leverage the user selection (e.g., input) and other user data to estimate physical measurements of the user (or the other person). That is, the technologies described herein can estimate physical measurements such as waist measurement, BMI, etc., without needing access to measuring devices. 
     Estimating physical measurements can be useful in various applications including, but not limited to, health and/or disease prevention applications, video gaming applications, online apparel shopping applications, law enforcement applications, etc. For instance, health and/or fitness products (e.g., Microsoft Band, Fitbit®, etc.) can utilize the technologies described herein to prompt users to select data items associated with graphical elements representing human bodies that they believe look most like themselves and to leverage the users&#39; selections overtime to estimate how the users&#39; bodies are changing and/or changes in physical measurements. This data can be correlated with other data collected from a health and/or fitness application (e.g., activity data, heart rate data, etc.) to enable users to track progress and enable users to see what activities, etc. impact their health and/or fitness. In other examples, the technologies described herein can be useful for disease identification and prevention. As described above, health professionals utilize physical measurements to predict whether a user is underweight, overweight, obese, etc., whether users are at risk for various diseases (e.g., cardiac, hypertension, diabetes, etc.), etc. Accordingly, the technologies described herein can be utilized to identify and prevent diseases without relying on measuring devices. 
     In additional or alternative examples, the technologies described herein can be utilized by gaming products and/or applications to generate realistic depictions of how users appear (i.e., avatars). For instance, the technologies described herein can prompt a user to select data items associated with graphical elements representing human bodies that they believe look most like themselves and can leverage the user&#39;s selections to generate realistic looking avatars. In other examples, the technologies described herein can be useful in online shopping applications. For instance, a user may not know his or her physical measurements. Accordingly, the technologies described herein can prompt a user to select data items associated with graphical elements representing human bodies that they believe look most like themselves and can leverage the user&#39;s selections to estimate physical measurements for recommending sizes of apparel. Additionally or alternatively, a user can be shopping online for a gift for another user (e.g., family member, friend, etc.) and he or she may not know the other user&#39;s physical measurements and/or size. Accordingly, the technologies described herein can prompt a user to select data items associated with graphical elements representing human bodies that they believe look most like the other user and can leverage the user&#39;s selections to estimate physical measurements for recommending sizes of apparel. 
     In yet another example, the technologies described herein can be useful for identifying suspected criminals/persons of interest and can therefore be useful for law enforcement applications. For instance, the technologies described herein can prompt a user to select data items associated with graphical elements representing human bodies that they believe look most like a suspect and can leverage the user&#39;s selections to estimate physical measurements for the suspect. The technologies described herein can also be used for searching through databases of data items associated with one or more graphical elements of known criminals. 
     Illustrative Environments 
       FIG. 1  is a schematic diagram showing an example environment  100  for utilizing data items associated with one or more graphical elements representing human bodies to estimate physical measurements. More particularly, the example environment  100  can include a service provider  102 , one or more network(s)  104 , one or more users  106 , and one or more devices  108  associated with the one or more users  106 . 
     The service provider  102  can be any entity, server(s), platform, etc., that facilitates presenting one or more sets of data items each associated with one or more graphical elements representing human bodies and leveraging inputs associated with individual data items to estimate physical measurements associated with users  106  and/or other persons (e.g., friends, family members, suspected criminals/persons of interest, etc.), as described above. The service provider  102  can be implemented in a non-distributed computing environment or can be implemented in a distributed computing environment, possibly by running some modules on devices  108  or other remotely located devices. As shown, the service provider  102  can include one or more server(s)  110 , which can include one or more processing unit(s)  112  and computer-readable media  114 , such as memory. In various examples, the service provider  102  can access data items associated with one or more graphical elements representing human bodies from a database, cause the data items to be presented to a user  106  in one or more sets of data items, receive data associated with user selection of individual data items, and leverage the magnitudes associated with the individual data items selected by the user  106  and other user data to estimate physical measurements associated with the user  106  and/or another person, as described above. The technologies described herein enable the service provider  102  to search and retrieve data items that are stored in the database and estimate physical measurements based on said data items more efficiently (i.e., faster) than if humans were involved, as described below. 
     In some examples, the network(s)  104  can be any type of network known in the art, such as the Internet. Moreover, the devices  108  can communicatively couple to the network(s)  104  in any manner, such as by a global or local wired or wireless connection (e.g., local area network (LAN), intranet, etc.). The network(s)  104  can facilitate communication between the server(s)  110  and the devices  108  associated with the users  106 . 
     In some examples, the users  106  can operate corresponding devices  108  (e.g., user devices) to perform various functions associated with the devices  108 , which can include one or more processing unit(s), computer-readable storage media, and a display  130 . Device(s)  108  can represent a diverse variety of device types and are not limited to any particular type of device. Examples of device(s)  108  can include but are not limited to stationary computers, mobile computers, embedded computers, or combinations thereof. Example stationary computers can include desktop computers, work stations, personal computers, thin clients, terminals, game consoles, personal video recorders (PVRs), set-top boxes, or the like. Example mobile computers can include laptop computers, tablet computers, wearable computers, implanted computing devices, telecommunication devices, automotive computers, portable gaming devices, media players, cameras, or the like. Example embedded computers can include network enabled televisions, integrated components for inclusion in a computing device, appliances, microcontrollers, digital signal processors, or any other sort of processing device, or the like. 
     Examples support scenarios where device(s) that can be included in the one or more server(s)  110  can include one or more computing devices that operate in a cluster or other clustered configuration to share resources, balance load, increase performance, provide fail-over support or redundancy, or for other purposes. Device(s) included in the one or more server(s)  110  can represent, but are not limited to, desktop computers, server computers, web-server computers, personal computers, mobile computers, laptop computers, tablet computers, wearable computers, implanted computing devices, telecommunication devices, automotive computers, network enabled televisions, thin clients, terminals, game consoles, gaming devices, work stations, media players, digital video recorders (DVRs), set-top boxes, cameras, integrated components for inclusion in a computing device, appliances, or any other sort of computing device. 
     Device(s) that can be included in the one or more server(s)  110  can include any type of computing device having one or more processing unit(s)  112  operably connected to computer-readable media  114  such as via a bus, which in some instances can include one or more of a system bus, a data bus, an address bus, a PCI bus, a Mini-PCI bus, and any variety of local, peripheral, and/or independent buses. Executable instructions stored on computer-readable media  114  can include, for example, a data collection module  116 , storing user data  118 , a database  120 , storing data items  122  associated with one or more graphical elements  123 A,  123 B, etc., representing human bodies, a measurement estimation module  124 , a presentation module  126 , a training module  128 , and other modules, programs, or applications that are loadable and executable by processing units(s)  112 . 
     Alternatively, or in addition, the functionality described herein can be performed, at least in part, by one or more hardware logic components such as accelerators. For example, and without limitation, illustrative types of hardware logic components that can be used include Field-programmable Gate Arrays (FPGAs), Application-specific Integrated Circuits (ASICs), Application-specific Standard Products (ASSPs), System-on-a-chip Systems (SOCs), Complex Programmable Logic Devices (CPLDs), etc. Device(s) that can be included in the one or more server(s)  110  can further include one or more input/output (I/O) interface(s) coupled to the bus to allow device(s) to communicate with other devices such as input peripheral devices (e.g., a keyboard, a mouse, a pen, a game controller, a voice input device, a touch input device, gestural input device, and the like) and/or output peripheral devices (e.g., a display, a printer, audio speakers, a haptic output, and the like). Such network interface(s) can include one or more network interface controllers (NICs) or other types of transceiver devices to send and receive communications over a network. For simplicity, some components are omitted from the illustrated environment. 
     Processing unit(s)  112  can represent, for example, a CPU-type processing unit, a GPU-type processing unit, a Field-programmable Gate Array (FPGA), another class of Digital Signal Processor (DSP), or other hardware logic components that can, in some instances, be driven by a CPU. For example, and without limitation, illustrative types of hardware logic components that can be used include Application-Specific Integrated Circuits (ASICs), Application-Specific Standard Products (ASSPs), System-on-a-chip systems (SOCs), Complex Programmable Logic Devices (CPLDs), etc. In various examples, the processing unit(s)  112  can execute one or more modules and/or processes to cause the server(s)  110  to perform a variety of functions, as set forth above and explained in further detail in the following disclosure. Additionally, each of the processing unit(s)  112  can possess its own local memory, which also can store program modules, program data, and/or one or more operating systems. 
     In at least one configuration, the computer-readable media  114  of the server(s)  110  can include components that facilitate interaction between the service provider  102  and the users  106 . The components can represent pieces of code executing on a computing device. For example, the computer-readable media  114  can include the data collection module  116 , the database  120 , the measurement estimation module  124 , the presentation module  126 , the training module  128 , etc. In at least some examples, the modules ( 116 ,  120 ,  126 ,  128 , etc.) can be implemented as computer-readable instructions, various data structures, and so forth via at least one processing unit(s)  112  to configure a device to execute instructions and to perform operations implementing generating response templates that correspond to ontological elements. Functionality to perform these operations can be included in multiple devices or a single device. 
     The computer-readable media  114  can also include the database  120  for storing data items  122  associated with one or more graphical elements  123 A,  123 B, etc. representing human bodies, as described above. As a non-limiting example,  FIG. 1  shows example data items  122  associated with one or more graphical elements  123 A,  123 B, etc. representing human bodies having a set of magnitudes. That is, the data items  122  can be associated with one or more graphical elements  123 A,  123 B, etc. that graphically represent human bodies that have proportions that are consistent with a human body having a set of physical measurements whereby each individual physical measurement corresponds to an individual magnitude, as described above. Each graphical element  123 A,  123 B, etc. can be associated with a different view of the human body having the set of magnitudes. As a non-limiting example,  FIG. 1  shows a data item  122 , where one of the graphical elements  123 A is a frontal view of a human body having a set of magnitudes and the other graphical element  124 B is a profile view of the human body having the set of magnitudes. The database of data items  122  can include different data items  122  based on different demographics (e.g., nationalities, ethnicities, genders, ages, etc.). 
     Depending on the exact configuration and type of the server(s)  110 , the computer-readable media  114  can include computer storage media and/or communication media. Computer storage media can include volatile memory, nonvolatile memory, and/or other persistent and/or auxiliary computer storage media, removable and non-removable computer storage media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules, or other data. Computer memory is an example of computer storage media. Thus, computer storage media includes tangible and/or physical forms of media included in a device and/or hardware component that is part of a device or external to a device, including but not limited to random-access memory (RAM), static random-access memory (SRAM), dynamic random-access memory (DRAM), phase change memory (PRAM), read-only memory (ROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), flash memory, compact disc read-only memory (CD-ROM), digital versatile disks (DVDs), optical cards or other optical storage media, miniature hard drives, memory cards, magnetic cassettes, magnetic tape, magnetic disk storage, magnetic cards or other magnetic storage devices or media, solid-state memory devices, storage arrays, network attached storage, storage area networks, hosted computer storage or any other storage memory, storage device, and/or storage medium that can be used to store and maintain information for access by a computing device. 
     In contrast, communication media can embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave, or other transmission mechanism. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. Such signals or carrier waves, etc. can be propagated on wired media such as a wired network or direct-wired connection, and/or wireless media such as acoustic, RF, infrared and other wireless media. As defined herein, computer storage media does not include communication media. That is, computer storage media does not include communications media consisting solely of a modulated data signal, a carrier wave, or a propagated signal, per se. 
     The data collection module  116  can receive data associated with users  106  (e.g., user data  118 ) from the users  106  and/or on behalf of the users  106  and/or access data associated with users  106  via third party sources and systems (e.g., social networks, professional networks, etc.). In some examples, users  106  can input user data  118  when they set up a user account or profile for interacting with the service provider  102 , an application, a website, etc., in response to a prompt for user data  118 , etc. In at least one example, the presentation module  126  can cause one or more user interfaces to be presented to the user  106 . The one or more user interfaces can provide functionality for the user  106  to input information. The user  106  can input personal information including, but not limited to, gender, age, physical measurements, etc., to the data collection module  116 . 
     In other examples, the data collection module  116  can receive data from devices such as input peripheral devices (e.g., sensors, cameras, and the like). For instance, a camera and/or sensor can determine a user&#39;s  106  height and provide data indicating the user&#39;s  106  height to the data collection module  116 . In additional or alternative examples, the data collection module  116  can infer user data  118  based on user interactions with the service provider  102 . For instance, a user  106  can select a data item  122  representative of a female out of a set of data items  122  representing both genders. Accordingly, the data collection module  116  can infer that the user  106  is a female. In some examples, the data collection module  116  can access user data  118  from third party sources and systems (e.g., social networks, professional networks, etc.). The user data  118  can be mapped to and/or otherwise associated with profiles that correspond to individual users  106 . The profiles that correspond to the individual users  106  can be stored in a database associated with the user data  118  and/or some other data repository. 
     The data collection module  116  can also receive data associated with user selections of data items  122  from sets of data items that are presented to the user  106 . In at least one example, the presentation module  126  can cause sets of data items to be presented to the user  106  via one or more personalized user interfaces, described below, that provide functionality for the user  106  to select individual data items  122  of the set of data items  122 . The user  106  can interact with the data items  122  that are presented via the user interface utilizing various mechanisms. In some examples, the user  106  can interact with the data items  122  via input peripheral devices (e.g., a keyboard, a mouse, a pen, a game controller, a voice input device, a touch input device, gestural input device, cameras, sensors, and the like), touch input, etc. The data collection module  116  can analyze the data to determine the magnitudes that correspond to each of the data items  122  selected by the user  106 . The data collection module  116  can log each input and associate the logs with a profile corresponding to the user  106  in the database associated with the user data  118  and/or other data repository. Each log can correspond to a set of magnitudes that are represented by the data item  122  that the user  106  selected. 
     The database  120  stores data items  122 , as described above. In at least one example, the data items  122  can be associated with one or more graphical elements that represent human bodies having different genders, heights, waist measurements, BMIs, etc. The data items  122 , as described above, can be associated with one or more graphical elements  123 A,  123 B, etc. that represent human bodies. The one or more graphical elements  123 A,  123 B, etc. associated with each data item  122  each represent a human body having a same set of magnitudes, as described above. The data items  122  illustrated in  FIG. 1  are examples of data items  122  that can be presented to users  106 , and any other presentation or configuration can be used. 
     The database  120  can be associated with an index, such as a lookup table, where the data items  122  can be indexed based on magnitudes and/or other characteristics (e.g., gender, etc.). In a non-limiting example, the data items  122  can be indexed by gender, height, dimension (e.g., waist measurement, BMI, etc.), etc. The index can expedite the time required to retrieve data items  122  from the database  120  and reduce runtime computations associated with retrieving the data items  122 . As a result, the index enables the data collection module  116  and/or presentation module  126  to retrieve data items  122  that are stored in the database  120  more efficiently (i.e., faster) then if humans were involved. 
     The measurement estimation module  124  accesses user data  118  and logs associated with data associated with selections of data items  122 . In at least one example, as described above, the user data  118  and logs can be mapped to and/or otherwise associated with a profile corresponding to a user  106  that is stored in the database associated with the user data  118 . In such examples, the measurement estimation module  124  can access the profile stored in the database for estimating physical measurements of a user  106 . The measurement estimation module  124  utilizes the user data  118  and magnitudes associated with the logs to estimate physical measurements associated with the user  106 . 
     The measurement estimation module  124  can utilize one or more predictive models to compute the estimated physical measurements. The one or more predictive models can change based on the dimensions to be estimated, population of users, demographic of the population of users, etc. Predictive Models 1 and 2, reproduced below, are non-limiting examples of predictive models that the measurement estimation module  124  can use for computing the estimated physical measurements (e.g., BMI and waist measurement, respectively). In each of the predictive models below, the weights (β x ) are based at least in part on training the predictive model described below using user data  118 , including previous inputs. Predictive Model 1 can be used to predict a user&#39;s  106  BMI (in kilograms/meters 2 ) and Predictive Model 2 can be used to predict a user&#39;s  106  waist measurement (in millimeters). The “selected_waist” and “selected_bmi” variables are determined from a most recent (e.g., the last) data item  122  selected by the user  106 . 
       predicted_bmi=β 0 +β 1  is_male+β 2  selected_bmi+β 3  selected_waist+β 4  selected_waist:selected_bmi  PREDICTIVE MODEL 1
 
       predicted_waist=β 0 +β 1  is_male+β 2  selected_bmi+β 3  selected_waist+β 4  selected_waist:selected_bmi  PREDICTIVE MODEL 2
 
     In both examples, selected_waist:selected_bmi denotes the product of the selected_waist and selected_bmi. 
     The presentation module  126  can generate user interfaces that provide various functionalities, as described above and also below. The presentation module  126  can cause a user interface to be presented to users  106  utilizing any communication channel, such as an e-mail message, a site (e.g., website) associated with the service provider  102 , a text message, a social network site, an application that is associated with the service provider  102  and that resides on device(s)  108  of the users  106 , etc. In at least one example, the presentation module  126  can generate a user interface that includes a set of data items (e.g., a subset of the data items  122  stored in the database  120 ). The user interface can be configured to receive input from the user  106  and/or on behalf of the user  106  indicating a selection of at least one data item  122  in the set of data items. The presentation module  126  can cause the user interface to be presented on a display  130  of a device  108 . 
     A non-limiting example of a user interface  132  is illustrated in  FIG. 1 . User interface  132  includes a set of data items  134 , as shown by the dashed lines. The set of data items  134  includes individual data items  122 , as described above. In  FIG. 1 , the data items  122  are associated with two graphical elements  123 A and  123 B that each represent a human body having a set of magnitudes (i.e., pairs of graphical elements). 
     In additional and/or alternative examples, the presentation module  126  can generate a user interface that prompts users  106  for user information such as gender, height, etc., and/or a user interface that presents estimated physical measurements to the users  106 . 
     The training module  128  can train the predictive model based at least in part on user data  118 , including determined physical measurements (e.g., physical measurements determined using a measuring device), data associated with user selections, and estimated physical measurements, as described in  FIG. 4  below. The predictive model can include a multiple regression model, etc., as described above in the non-limiting examples of Predictive Model 1 and Predictive Model 2. 
     Example Processes 
     The processes described in  FIGS. 2-4  below are illustrated as a collection of blocks in a logical flow graph, which represent a sequence of operations that can be implemented in hardware, software, or a combination thereof. In the context of software, the blocks represent computer-executable instructions stored on one or more computer-readable storage media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures, and the like that perform particular functions or implement particular abstract data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described blocks can be combined in any order and/or in parallel to implement the processes. 
       FIG. 2  is a flow diagram that illustrates an example process  200  to estimate physical measurements utilizing data items  122  associated with one or more graphical elements  123 A,  123 B, etc. representing human bodies that are presented to users  106 . 
     Block  202  illustrates receiving user data  118 . The data collection module  116  can receive data (e.g., user data  118 ) associated with users  106  from the users  106  and/or on behalf of the users  106  and/or access data associated with users  106  via third party sources and systems (e.g., social networks, professional networks, etc.), as described above. In at least one example, the presentation module  126  can generate a user interface that prompts a user  106  to input his or her gender and height as illustrated in the user interface associated with block  202 . Additional and/or alternative user interfaces can be presented for prompting the user  106  for additional and/or alternative information. The presentation module  126  can cause the user interface to be presented to a user  106  via a display  130  of a device  108 , as described above. A user  106  can indicate whether he or she is a male or female, respectively, and select his or her height from one or more drop down menus. 
     The user interface associated with block  202  is an example of a user interface that can be presented to users  106  and any other presentation or configuration can be used. In  FIG. 2 , the user  106  has indicated that he is a male and is 5′11″ tall. The data collection module  116  can send data associated with the user&#39;s input (e.g., gender, height, etc.) to the presentation module  126 . 
     In some examples, process  200  can be executed without a user  106  indicating whether he or she is male or female, respectively, or specifying his or her height. 
     Block  204  illustrates causing a set of data items  134  to be presented to a user  106 . In at least one example, the presentation module  126  can receive user data  118  from the data collection module  116  and, leveraging the index associated with the database  120  described above, the presentation module  126  can retrieve data items  122  and generate a user interface that includes a set of data items  134  associated with the user&#39;s input (e.g., gender, height, etc.). In an example, the set of data items  134  can represent a subset of data items  122  stored in the database  120  that represent human bodies having a same set of magnitudes with respect to every dimension except one dimension. That is, the set of data items  134  can include data items  122  that represent human bodies with different magnitudes associated with one dimension, but otherwise have the same set of magnitudes. In at least one example, based at least in part on receiving the input indicating the gender and height of the user, the presentation module  126  can access a predetermined number of data items  122  associated with the same gender and height as the user  106 . The predetermined number can be determined on a number of data items  122  that can be arranged on a user interface, an arbitrary number, etc. 
     Each data item  122  in a set of data items  134  can be associated with one or more graphical elements that represent a human body with a different magnitude for a dimension than each of the other data items  122  in the set of data items  134 . As a non-limiting example, each data item  122  in a set of data items  134  can be associated with one or more graphical elements that represent a male who is 5′11″; however, each data item  122  can be associated with one or more graphical elements that can represent a 5′11″ male with a different waist measurement. In at least one example, each data item  122  can be associated with other magnitudes that are associated with standardized measurements associated with a population, as described below. For instance, each data item  122  can be associated with one or more graphical elements that represent a human body with a standardized BMI. 
     In additional and/or alternative examples, the set of data items  134  can represent a set of data items  134  stored in the database  120  that represent human bodies having a different sets of magnitudes with respect to different dimensions. For instance, in some examples, the presentation module  126  can retrieve data items  122  and generate a user interface that includes a set of data items  134  arranged in a matrix arrangement in which one axis is associated with BMI and the other axis is associated with waist measurement. That is, the data items  122  represent human bodies with different BMIs along one axis and the data items  122  represent human bodies with different waist measurements along the other axis. In other examples, the presentation module  126  can retrieve data items  122  and generate a user interface that includes a set of data items  134  with varying dimensions that can be presented in a pattern, a random configuration, etc. For instance, in at least one example, the set of data items  134  can include all of the data items  122  stored in the database  120  and the presentation module  126  can present all of the data items  122  to the user  106 . 
     Block  206  illustrates receiving data associated with a user selection. A user  106  can interact with a user interface to indicate which data item  122  of the set of data items  134  is associated with at least one graphical element representing a human body that looks most similar to him or her, as described above. In at least some examples, users  106  can leverage zoom features to enlarge the individual data items  122 . The device  108  can determine an input associated with the user selection. As a non-limiting example, box  206  indicates that the user selected the data item  122  within the box  206  as the pair of graphical elements  123 A,  123 B, etc. that are most representative of his body or of the body of another person. The device  108  can send data associated with the input to the data collection module  116 . The data collection module  116  can receive the data and can analyze the input to determine the set of magnitudes associated with the data item  122  selected by the user  106 . The data collection module  116  can send the data associated with the set of magnitudes to the measurement estimation module  124  and/or the presentation module  126 . 
     Block  208  illustrates estimating physical measurements. The measurement estimation module  124  accesses user data  118  and receives and/or accesses the logs associated with the data indicating a selection of the data item  122  that represents at least one graphical element of a human body that best represents the user&#39;s  106  own body. In additional and/or alternative examples, the measurement estimation module  124  can access user data  118  and receive and/or access the logs associated with the data indicating a selection of the data item  122  that represents at least one graphical element of a human body that best represents a body of another person (e.g., a friend, a family member, a suspected criminal/person of interest, etc.), as described above. The measurement estimation module  124  can utilize a predictive model (e.g., Predictive Model 1, Predictive Model 2, etc.) to compute estimated physical measurements based at least in part on the user data  118  (e.g., gender, height, etc.) and the magnitudes associated with user selections of data items  122 . In at least one example, the measurement estimation module  124  can estimate at least a waist measurement and/or BMI using a predictive model, like Predictive Models 1 and 2 described above. 
     Block  210  illustrates causing the physical measurements to be presented to the user  106 . The presentation module  126  can generate a user interface that provides functionality to present estimated physical measurements to the user  106  via the display  130  of the device  108 . The presentation module  126  can send the user interface to the device  108  for presenting the user interface to the user  106  on the display  130  of the device  108 . An example user interface is associated with block  210 . The user interface associated with block  210  is an example of a user interface that can be presented to users  106  and any other presentation or configuration can be used. 
     The physical measurements can be presented to the user  106  as finite physical measurements, ranges of physical measurements, physical measurements including a confidence interval, etc. As a non-limiting example, the physical measurements are presented as physical measurements including confidence intervals. For instance, the measurement estimation module  124  estimated the waist measurement of the user  106  represented in  FIG. 2  as 868.9 millimeters with a confidence interval of ±100 millimeters. That is, the user&#39;s  106  waist is likely to measure 768.9-968.9 millimeters. One or more graphical representations can also be presented with the physical measurements to visually represent physical measurements associated with the user  106 . 
     Block  212  illustrates iteratively causing sets of data items  134  to be presented to the user  106  and iteratively receiving data associated with the user selections. In at least some examples, based at least in part on receiving data associated with a first input, the presentation module  126  can receive and/or access data from the data collection module  116  that is associated with the magnitudes of the data item  122  selected by the user  106  and can leverage the index associated with the database  120  to retrieve a new set of data items  134 . The new set of data items  134  can include a same number of data items  122  as the first set of data items  134 , more data items  122 , or fewer data items  122 . The presentation module  126  can generate a user interface that includes the new set of data items  134  that are associated with one or more graphical elements that represent human bodies with at least some new magnitudes. 
     Data items  122  in the new set of data items  134  can each be associated with one or more graphical elements that represent human bodies with at least one magnitude associated with a dimension that is different from the other data items  122  in the new set of data items  134  but otherwise have the same magnitudes as the other data items  122  in the new set of data items  134  with respect to other dimensions. In some examples, at least one of the magnitudes associated with all of the data items  122  in the new set of data items  134  is determined based at least in part on a magnitude associated with the data item  122  selected by the user  106  in the first set of data items  134 . The presentation module  126  can cause a user interface associated with the new set of data items  134  to be presented on a display  130  of a device  108 , as described above. 
     In at least one example, based at least in part on receiving data associated with the first input indicating which data item  122  in a set of data items  134  is associated with at least one graphical element that represents a human body that best represents the user  106 , the data collection module  114  can analyze the selection and determine the magnitudes associated with the data item  122  selected by the user  106 . The data collection module  114  can log each of the inputs and associate the logs with the profile corresponding to the user  106  in the database associated with the user data  118  and/or other data repository. For instance, if the user  106  selected a data item  122  associated with a graphical element that represents a human body with a waist measurement of 35 inches, the data collection module  114  can associate that log the corresponds to the user selection with the user profile corresponding to the user  106 . 
     Based at least in part on determining the magnitudes associated with the data item  122  selected by the user  106 , the presentation module  126  can access a predetermined number of data items  122  that are associated with the same gender, height, and magnitude (e.g., waist measurement of 35 inches) to select a new set of data items  134 . The new set of data items  134  can include data items  122  that are associated with graphical elements that represent human bodies that have different magnitudes associated with a different dimension than the data items  122  in the first set of data items  134 . 
     As a non-limiting example, if the data items  122  of the first set of data items  134  are associated with one or more graphical elements that represent human bodies that each have a waist measurement, the data items  122  of the new set of data items  122  can be associated with one or more graphical elements that represent human bodies that are associated with one or more graphical elements that represent human bodies that each have a different BMI. As such, in the non-limiting example, the new set of data items  122  can be associated with graphical elements that represent human bodies that have a same gender, same height, waist measurement, and varying BMIs. Each data item  122  can be associated with at least one graphical element that represents a human body with a different magnitude for the new dimension (e.g., BMI). As a non-limiting example, every data item  122  in the new set of data items  134  can be associated with graphical elements that represent a male who is 5′11″ with a waist measurement of 35 inches; however, each data item  122  can be associated with graphical elements that represent a 5′11″ male with a waist measurement of 35 inches and a different BMI. 
     In at least one example, a new set of data items  134  can include at least one data item  122  that was in the first set of data items  134 . For instance, as a non-limiting example, the first set of data items  134  can be associated with data items  122  associated with one or more graphical elements that represent human bodies that have a same gender, same height, same BMIs, and various waist measurements. The user can select a data item  122  associated with a graphical element representing a human body having a BMI of 26 and a waist measurement (e.g., 35 inches). Accordingly, the new set of data items  134  can be associated with data items  122  associated with one or more graphical elements representing a human body having a waist measurement of 35 inches and varying BMIs, including the BMI associated with the data items  122  in the first set of data items  134  (e.g., 26). Therefore, in at least one example, a data item  122  in an immediately preceding set of data items  134  can also be included in the new set of data items  134 . 
     The presentation module  126  can iteratively define new sets of data items  134  to be presented to the user  106 . As described above, each new set of data items  134  can be associated with data items  122  that are associated with one or more graphical elements that represent human bodies that have a different magnitude associated with a new dimension. The presentation module  126  can cause the sets of data items  134  to be presented to the user  106  via a user interface configured to receive input. Based at least in part on causing the sets of data items  134  to be presented to the user  106 , the device  108  can determine inputs and send data corresponding to the inputs to the data collection module  114 . The data collection module  114  can receive inputs indicating which data item  122  is associated with at least one graphical element that best represents the user  106 . The measurement estimation module  124  can leverage the user data  118 , including the data associated with the inputs, and the predictive model to estimate the physical measurements associated with the user  106 , as described above. In some examples, the measurement estimation module  124  can leverage the user data  118 , including the data associated with the inputs, and the predictive model to estimate the physical measurements associated with another person, as described above. 
       FIG. 3  is a flow diagram that illustrates another example process  300  to estimate physical measurements utilizing data items  122  associated with graphical elements that represent human bodies that are presented to users  106 . 
     Block  302  illustrates determining user data  118 . The data collection module  116  can receive data associated with users  106  from the users  106  and/or on behalf of the user  106  and/or access data associated with users  106  via third party sources and systems (e.g., social networks, professional networks, etc.), as described above. In at least one example, the presentation module  126  can generate a user interface that prompts a user  106  for his or her gender, height measurement, and/or other dimensions, as described above. 
     Block  304  illustrates causing a first set of data items  122  to be presented to the user  106 . In at least one example, the presentation module  126  can access user data  118  and can utilize the index associated with the database  120  to retrieve data items  122  associated with one or more graphical elements that represent human bodies with at least some of the same physical measurements as the user  106  (per the user data  118 ). The presentation module  126  can utilize the retrieved data items  122  to generate a user interface that includes a first set of data items  134 . The user interface can be configured to receive user selection of one or more data items  122 . 
     In at least one example, based at least in part on receiving the input indicating the gender and height of the user  106 , the presentation module  126  can retrieve a predetermined number of data items  122  associated with graphical elements that represent human bodies that are associated with the same gender and height. Each data item  122  in the first set of data items  134  can be associated with one or more graphical elements that represent a human body with at least one different magnitude for a dimension and same magnitudes for each of the other dimensions. 
     As a non-limiting example, each data item  122  in the first set of data items  134  associated with block  304  can be associated with one or more graphical elements that represent a human body of the same gender and height, but each data item  122  can have a different waist measurement. In at least one example, each data item  122  can be associated with one or more graphical elements that represent human bodies that have a same predetermined BMI. In at least one example, the predetermined BMI can be a standardized BMI (e.g., average, median, etc.) for a population of users who have been previously measured. That is, each data item  122  can be associated with graphical elements that represent human bodies with a gender and a height that are the same as the user  106 , a same predetermined BMI, and a different waist measurement. 
     Block  306  illustrates receiving data associated with a first input. A user  106  can interact with a user interface to indicate which data item  122  of the first set of data items  134  is associated with one or more graphical elements that look most similar to him or her. As described above, in some examples, a user  106  can interact with a user interface to indicate which data item  122  of the second set of data items  134  is associated with one or more graphical elements that look most similar to another person (e.g., a friend, a family member, a suspected criminal/person of interest, etc.). 
     As a non-limiting example, box  306  indicates that the user  106  selected the data item  122  within the box  306  as the data item  122  associated with graphical elements most representative of his body. The device  108  can determine the selection and can send data corresponding to the input to the data collection module  116 . The data collection module  116  can receive the data associated with the first input and can determine the magnitudes associated with the data item  122  selected by the user  106  in the first input. The data collection module  116  can log the first input and associate the log with the user profile corresponding to the user  106 . The data collection module  116  can send data associated with the first input (e.g., the magnitudes associated with the data item  122  selected by the user  106 ) to the presentation module  126 . 
     Block  308  illustrates causing a second set of data items  134  to be presented to the user  106 . As described above, the presentation module  128  can iteratively cause additional sets of data items  134  to be presented to the user  106 . In at least one example, based at least in part on receiving the first input  306  indicating which data item  122  is associated with one or more graphical elements that best represent the user  106 , the data collection module  114  can analyze the selection and determine the magnitudes associated with the data item  122  selected by the user  106 , as described above. The presentation module  126  can receive data associated with the input  306  (e.g., the magnitudes associated with the data item  122  selected by the user  106 ) and can utilize the data and the index associated with the database  120  to access a predetermined number of data items  122  that represent human bodies having the same gender, height, and set of magnitudes, with the exception of magnitudes associated with one dimension. The second set of data items  134  can be associated with one or more graphical elements that represent human bodies that have different magnitudes associated with a different dimension than the first set of data items  134 . 
     As a non-limiting example, if the data items  122  in the first set of data items  122  are associated with one or more graphical elements that represent human bodies that have different waist measurements, the data items  122  in the second set of data items  134  can be associated with one or more graphical elements that represent human bodies that have a different BMI. Each data item  122  can represent a human body with a different magnitude for the dimension. For instance, each data item  122  can be associated with one or more graphical elements that represent a human body with a height and gender that is the same as the user  106 , a waist measurement that corresponds to the waist measurement associated with the previously selected data item  122 , and a different BMI. In some examples, as described above, one of the data items  122  in the second set of data items  134  can have a same BMI as the data item  122  selected in the first set of data items  134 . 
     Block  310  illustrates receiving data associated with a second input from the user  106 . A user  106  can interact with a user interface to indicate which data item  122  of the second set of data items  134  is associated with one or more graphical elements that look most similar to him or her. As described above, in some examples, a user  106  can interact with a user interface to indicate which data item  122  of the second set of data items  134  is associated with one or more graphical elements that look most similar to another person (e.g., a friend, a family member, a suspected criminal/person of interest, etc.). 
     As a non-limiting example, the box  310  indicates that the user  106  selects the data item within the box  310  as the data item associated with one or more graphical elements that are most representative of his body. The device  108  can determine the user selection and can send data associated with the second input to the data collection module  116 . The data collection module  116  can receive the data associated with the second input and can determine the magnitude associated with the data item  122  selected by the user  106 . The data collection module  116  can log the second input and associate the log with the user  106  in the user data  118 . The data collection module  116  can send data associated with the second input (e.g., the magnitudes associated with the data item  122  selected by the user  106 ) to the presentation module  126 . 
     Block  312  illustrates causing a third set of data items  134  to be presented to the user  106 . As described above, the presentation module  128  can iteratively cause additional sets of data items  134  to be presented to the user  106 . In at least one example, based at least in part on receiving data associated with the second input indicating data item  122  is associated with one or more graphical elements that best represent the user  106 , the data collection module  114  can analyze the selection and determine the magnitudes associated with the data item  122  selected by the user  106 , as described above. The presentation module  126  can receive data associated with the second input (e.g., the magnitudes associated with the data item  122  selected by the user  106 ) and can utilize the data and the index associated with the database  120  to access a predetermined number of data items  122  that are associated with one or more graphical elements that represent human bodies having the same gender, height, and set of magnitudes, with the exception of magnitudes associated with one dimension. The third set of data items  134  can be associated with one or more graphical elements that represent human bodies that have different magnitudes associated with a different dimension than the first set and/or second set of data items  134 . 
     As a non-limiting example, if the second set of data items  134  are associated with one or more graphical elements that represent human bodies that have a different BMI, the third set of data items  134  can be associated with one or more graphical elements that represent human bodies that have a different waist measurement and/or other magnitude associated with another dimension. Each data item  122  can be associated with one or more graphical elements that represent a human body with a different magnitude for the dimension. For instance, data item  122  can be associated with one or more graphical elements that represent a human body with a height and gender that is the same as the user  106 , a BMI that corresponds to the BMI associated with the previously selected graphical element  122 , and different waist measurements (or other dimension). 
     Block  314  illustrates receiving data associated with a third input. A user  106  can interact with a user interface to indicate which data item  122  of the third set of data items  134  is associated with one or more graphical elements that look most similar to him or her. As described above, in some examples, a user  106  can interact with a user interface to indicate which data item  122  of the second set of data items  134  is associated with one or more graphical elements that look most similar to another person (e.g., a friend, a family member, a suspected criminal/person of interest, etc.). 
     As a non-limiting example, the box  314  indicates that the user  106  selects the data item  122  within the box  314  as the data item  126  associated with one or more graphical elements that are most representative of his body. The device  108  can determine the user selection and can send data associated with the third input to the data collection module  116 . The data collection module  116  can receive the third input and can determine the magnitudes associated with the data item  122  selected by the user  106 . The data collection module  116  can log the third input and associate the log with the user  106  in the user data  118 . The data collection module  116  can send data associated with the third input (e.g., the magnitudes associated with the data item  122  selected by the user  106 ) to the measurement estimation module  124 . 
     Block  316  illustrates estimating physical measurements associated with the user  106  or the other person, as described above. The measurement estimation module  124  accesses user data  118  including inputs indicating a selection of at least one data item  122  associated with one or more graphical elements that that best represents the user&#39;s  106  body. In additional and/or alternative examples, the measurement estimation module  124  can access user data  118  including inputs indicating a selection of at least one data item  122  associated with one or more graphical elements that that best represents another person&#39;s body. The measurement estimation module  124  can utilize a predictive model (e.g., Predictive Model 1, Predictive Model 2, etc.) to compute estimated physical measurements based at least in part on the user data  118  (e.g., user gender, height, etc.) and the inputs. In at least one example, the measurement estimation module  124  can estimate at least a waist measurement and/or BMI using a predictive model like the predictive models described above. 
     Process  300  includes three iterations of causing sets of data items  122  to be presented to users  106  and receiving data associated with inputs, but any number of iterations can be used to estimate physical measurements. In some examples, the data collection module  116  can receive data associated with inputs following each presentation of a set of data items  134  and can subsequently send the data associated with each input to the measurement estimation module  124 . In other examples, after the last iteration, the data collection module  116  can receive data associated with a last input (e.g., the magnitudes associated with the last data item  122  selected by the user  106 ) and can subsequently send the data to the measurement estimation module  124  for estimating the physical measurements. 
       FIG. 4  is a flow diagram that illustrates an example process  400  to train a predictive model. 
     Block  402  illustrates accessing user data  118  and data associated with inputs. The training module  128  can receive and/or access user data  118  from the data collection module  116 . In at least one example, the training module  128  can access determined physical measurements associated with users  106  (i.e., physical measurements ascertained by measurement devices). Additionally, the training module  128  can access data associated with inputs associated with users  106 . As described above, the inputs can be associated with user selections of data items  122  from each set of data items  134  caused to be presented to the user  106 . The determined physical measurements and the data associated with the inputs can be associated with profiles corresponding to the users  106  and stored in the database associated with the user data  118  and/or some other data repository associated with the user data  118 . 
     Block  404  illustrates accessing estimated physical measurements. The training module  128  can access the estimated physical measurements determined by the measurement estimation module  124 . The estimated physical measurements can also be associated with each individual user  106  and/or the determined physical measurements and data associated with the inputs. 
     Block  406  illustrates training predictive models. The training module  128  can leverage machine learning algorithms (e.g., supervised learning, unsupervised learning, semi-supervised learning, deep learning, etc.) to learn predictive models. The measurement estimation module  124  can leverage the predictive models to estimate physical measurements based at least in part on one or more determined physical measurements and the inputs. Predictive Model 1 and Predictive Model 2, described above, are examples of predictive models learned using the machine learning algorithms.
