       FIG. 1  is a conceptual diagram of collecting data for classifying a plurality of electronic devices related to the present disclosure. 
     An electronic device  120  according to one embodiment of the present disclosure may include an interface unit, a power supply unit, a memory, a controller, and the like. The above components are not essential to implement an electronic device, and thus, the electronic device described herein may have more or fewer components than those listed above. 
     In more detail, the interface unit may include at least one module for receiving information from a user. For example, the interface unit may include a camera or video input unit for inputting a video signal, a microphone or an audio input unit for inputting an audio signal, a key input unit (for example, a touch key, a push key, touch screens, etc.), or the like. Hereinafter, modules for receiving information from the user will be referred to as an input unit. 
     In addition, the interface unit may include at least one module for generating an output related to visual, hearing, and the like. For example, the interface unit may include at least one of a display unit, a sound output unit, and a light output unit. Here, the display unit may be formed in a mutual layer structure or may be formed integrally with a touch sensor, thereby implementing a touch screen. The touch screen may function as an input interface between the electronic device  120  and the user and simultaneously, provide an output interface between the electronic device  120  and the user. Hereinafter, at least one module configured to generate an output related to the visual, hearing, or the like will be referred to as an output unit. 
     In addition, the interface unit may include at least one biometric sensor configured to obtain biometric information from the user. For example, the biometric sensor may include at least one of a fingerprint sensor, an iris sensor, a face recognition sensor, a PhotoPlethysmoGraphy (PPG) sensor, and a voice sensor. The biometric sensor may obtain biometric information (for example: fingerprint, iris, face image, heart rate, etc.) from the user. Hereinafter, the at least one biometric sensor will be referred to as a sensor unit. 
     Meanwhile, the electronic device  120  may be connected to the controller at a remote or short distance via a predetermined communication method. For example, the electronic device  120  may communicate with a server via Near Field Communication, wireless Internet methods such as Wireless LAN (WLAN) and Wireless-Fidelity (Wi-Fi), mobile communication methods such as Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), 5G network (new radio or millitmeter (MM) wave) or the like. Although not shown for this purpose, each electronic device may include a communication unit configured to communicate with a server. 
     For example, the electronic device  120   a  may include a mobile terminal of a user. In this case, a touch screen and a speaker of the mobile terminal may be the output unit, and a keypad (or touch keypad) or the like may be the input unit. Further, a camera or a fingerprint sensor provided at the mobile terminal to be capable of recognizing an iris or face of a user may be the sensor unit. Furthermore, the electronic device  120   b  may be a mechanical device (hereinafter, referred to as an air conditioner) for lowering a room temperature or maintaining a comfortable state. 
     Meanwhile, as shown in  FIG. 1 , a plurality of electronic devices  120   a  and  120   b  may perform wireless communication with a server  140  having a separate memory  130 . 
     The server  140  may include a wireless communication unit configured to perform wireless communication with a plurality of electronic devices and a memory  130  configured to store data received from the plurality of electronic devices. 
     The memory  130  is typically implemented to store data to support various functions or features of the electronic device  120 . For instance, the memory  130  may be configured to store application programs executed in the electronic device  120 , data or instructions for operations of the electronic device  120 , and the like. At least one of these application programs may be downloaded from the server  140  via wireless communication. Other application programs may be installed within the electronic device  120  at the time of manufacturing or shipping, which is typically the case for basic functions of the electronic device  120  (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). Meanwhile, the application program may be stored in the memory  130 , installed on the electronic device  120  via wireless communication, and driven to perform an operation (or function) of the electronic device by a controller provided at the electronic device. 
     Meanwhile, the controller provided at the electronic device  120  controls the overall operation of the electronic device  120  typically. The controller provided at the electronic device  120  may process signals, data, information, and the like input or output via the above-described components, or drive an application program stored in the memory provided in the electronic device, thereby providing and processing information or functions appropriate to a user. 
     The controller provided at the electronic device  120  may operate at least two or more of the components included at the electronic device  120  in combination with each other to drive the application program. 
     The user may set the electronic device  120  at a predetermined state via the input unit or the sensor unit. The controller provided at the electronic device  120  sets the electronic device  120  at a specific state after receiving information from the user via the input unit or the sensor unit. 
     Here, setting the electronic device  120  refers that the controller controls the components provided at the electronic device  120  with a control command corresponding to a user input. In detail, allowing the electronic device  120  to implement a specific function by a user input may be defined as the setting of the electronic device  120 . For example, when the electronic device  120  is a mobile terminal, outputting voice information corresponding to a specific audio file from a mobile terminal by a user input may be regarded as setting the electronic device  120 . 
     Meanwhile, the setting of the electronic device  120  is not limited thereto and may be defined as maintaining the electronic device  120  at a specific state by a user input. For example, when the electronic device  120  is a mobile terminal, adjusting screen brightness of a display device provided at the mobile terminal by a user input may be regarded as the setting of the electronic device  120 . 
     As described above, the setting of the electronic device  120  includes all embodiments in which a user input is made and a controller provided at the electronic device  120  controls the electronic device  120  in response to the user input. 
     Meanwhile, the user input is not limited to the above-described input unit and the sensor unit, and may be made remotely via a separate device. For example, the user input may be made via a remote controller. In this case, the electronic device  120  may further include a separate receiver for receiving information from the remote controller. 
     Meanwhile, the memory  130  provided at the server  140  may include a database that stores data collected from a plurality of electronic devices  120 . Here, the database may include a setting value with respect to the electronic device  120 . 
     Here, the setting value may include data input from a user when the electronic device is set, control command data corresponding to the user input, data defining a result of executing the control command at the electronic device, and the like. That is, the setting value is data defining how the user used the electronic device. 
     Meanwhile, the server  140  includes a controller configured to classify the plurality of electronic devices  120  into a plurality of clusters. Hereinafter, a method of classifying a plurality of electronic devices  120  into a plurality of clusters by the controller provided at the server  140  will be described. 
     The present disclosure is implemented via wireless communication between a server and a plurality of electronic devices. 
       FIG. 2  is a conceptual diagram illustrating wireless communication between a server and an electronic device according to the present disclosure, and  FIG. 3  is a conceptual diagram illustrating one embodiment in which a server according to the present disclosure classifies a plurality of electronic devices into a plurality of clusters. 
     First, collecting data via wireless communication between the server and the electronic device will be described. 
     Referring to  FIG. 2 , the plurality of electronic devices  120   a  to  120   d  transmit a setting value of the electronic device to the server (S 220 ). Here, the setting value may be user input data as it is, a control command generated by user input data, or data defining a result of performing the control command. 
     The setting value may be transmitted to the server whenever a user input is applied (S 210 ) or may be transmitted to the server  140  only when a user input that satisfies a predetermined condition is applied. 
     In detail, after the electronic device  120  is activated, the electronic device  120  may transmit only the setting value corresponding to the first user input to the server  140 . Here, the activating of the electronic device  120  refers that the electronic device  120  is switched to a state in which power is supplied while power is not supplied to the electronic device  120 , or the electronic device  120  is switched to a state in which the electronic device  120  may perform all the functions that may be implemented at the electronic device  120  while only a minimum power is supplied to the electronic device  120  (for example, a power saving mode). However, the present disclosure is not limited thereto, and the activating of the electronic device  120  refers that the electronic device  120  is switched to a state capable of performing a specific function in response to a user input. 
     In one embodiment, when the electronic device  120  is an air conditioner, after power is supplied to the air conditioner, the air conditioner may transmit data related to at least one of a target temperature value, a wind direction value, and a wind strength value input first by the user to the server. 
     In another embodiment, when the electronic device is a clothing laundry device (hereinafter, referred to as a washing machine), the washing machine may transmit data related to at least one of a washing time, washing temperature, washing intensity, rinsing time, rinsing frequency, rinsing intensity, a dewatering time, and a dewatering intensity input by the user for washing, to the server. 
     The server stores the setting value received from the electronic device in the memory  130 . The server collects the setting values repeatedly and then generates cluster data. 
     As the clustering algorithm, K-Means Clustering, Mean-Shift Clustering, Density-Based Spatial Clustering of Applications with Noise, Expectation-Maximization using Gaussian Mixture Models (GMM), Agglomerative Hierarchical Clustering, etc. may be used, but the present disclosure is not limited thereto. 
     In the above-described method, the server  140  classifies the plurality of electronic devices into any one of the plurality of clusters based on the setting values received from the plurality of electronic devices. 
     In one embodiment, the server  140  may classify a plurality of air conditioners into one of three clusters by using a target temperature setting value received from the plurality of air conditioners. In detail, as shown in  FIG. 3 , the server  140  may classify a plurality of air conditioners into cluster A to set a relatively low target temperature, cluster B to set the target temperature relative to a measured temperature, and cluster C to set the target temperature relatively high. 
     Meanwhile, the server  140  calculates representative setting values for each of the plurality of clusters. For example, when the electronic device is an air conditioner, the representative setting value may be data including a target temperature value, a wind direction value, and a wind strength value. The representative setting value may be an average value of setting values received from an electronic device classified into a specific cluster, but is not limited thereto. 
     For example, the server  140  may set 22° C. as a representative setting value for cluster A, 2° C. lower than a current temperature as a representative setting value for cluster B, and 28° C. as a representative setting value for cluster C. 
     As described above, the server classifies the electronic device into a specific cluster based on a setting value corresponding to a user input applied first after the electronic device is activated, and calculates a representative setting value corresponding to the specific cluster. 
     In this manner, the present disclosure may cluster the users of a similar tendency by using the user input that the user unconsciously inputs after the electronic device is activated. 
     Meanwhile, the present disclosure enables the electronic device  120  to be set automatically by using the cluster data formed in the above-described manner. Hereinafter, a method of controlling the electronic device by using the above-described cluster data will be described. 
       FIG. 4  is a conceptual diagram illustrating a method of controlling an electronic device by using cluster data formed in a server according to the present disclosure. 
     The conceptual diagram described in  FIG. 4  is based on the premise that the server is in a state in which cluster data is formed after a setting value is received from a plurality of electronic devices. That is, the conceptual diagram described in  FIG. 4  is based on the premise that the server  140  is in a state in which a plurality of electronic devices has already been classified into different clusters and a representative setting value with respect to each cluster is calculated. 
     Meanwhile, the electronic device  120  described in  FIG. 4  is in a state in which the electronic device  120  is not classified into a specific cluster via the server  140 . That is, the electronic device  120  described with reference to  FIG. 4  is a device immediately after shipment, or an electronic device in which a linkage with the server  140  is not set. 
     A user may set a linkage with the server  140  at a specific application installed at the electronic device  120 . The specific application may be an application installed at the shipment or an application installed via downloading from a predetermined server. 
     When the electronic device  120  is linked with the server  140 , whenever the electronic device  120  is activated, the electronic device  120  transmits a setting value of the electronic device  120  to the server  140 . In detail, the electronic device  120  transmits to the server (S 320 ) a setting value corresponding to a user input applied first (S 310 ) after the electronic device  120  is activated. 
     When the server  140  receives a setting value from the electronic device  120 , the server  140  determines a cluster to classify the electronic device  120 . In one embodiment, the server  140  may classify the electronic device  120  into a specific cluster by using a setting value received first from the electronic device  120 . 
     In another embodiment, when the server  140  receives a setting value a predetermined number of times or more from the electronic device  120  (S 330 ), the server  140  may classify the electronic device  120  into a specific cluster (S 340 ). In this case, the server  140  may classify the electronic device  120  into a specific cluster based on the average value of a plurality of setting values received from the electronic device  120  or classify the electronic device  120  into a specific cluster based on a mode of the setting values. However, the present disclosure is not limited thereto. 
     In another embodiment, when the setting values received from the electronic device  120  have a predetermined pattern, the server  140  may classify the electronic device  120  into a specific cluster. For example, when a deviation of the setting values received from the electronic device  120  is within a predetermined level, the server  140  may classify the electronic device  120  into a specific cluster. In this manner, the present disclosure enables the electronic device  120  to be classified into a specific cluster only when the electronic device  120  is used in a predetermined pattern. 
     Meanwhile, when the electronic device  120  is classified into a specific cluster, the server  140  transmits the classified cluster data and a representative setting value corresponding to the classified cluster data to the electronic device  120  (S 350 ). However, the present disclosure is not limited thereto, and the server  140  may transmit only the representative setting value corresponding to the classified cluster data to the electronic device  120 . 
     When the electronic device is activated after receiving the classified cluster data and the representative setting value corresponding to the classified cluster data (S 360 ), the controller provided at the electronic device performs a control corresponding to the representative setting value. 
     As one embodiment, a case in which the electronic device  120  is an air conditioner will be described. When the air conditioner and the server are linked to each other, the air conditioner transmits a setting value corresponding to a user input applied first after power is applied, to the server. 
     When the server receives the setting value a predetermined number of times or more from the air conditioner, the server may classify the air conditioner into any one of three clusters. Here, the three clusters may be classified according to a target temperature value of the air conditioner. For example, the three clusters may be classified into a cluster to set the target temperature to 22° C., a cluster to set the target temperature to 2° C. lower than a measured temperature, and a cluster to set the target temperature to 28° C. 
     The server classifies the air conditioner into any one of the three clusters. Then, the server transmits a representative setting value corresponding to the classified cluster to the air conditioner. For example, when the air conditioner is classified into the cluster that sets the target temperature to 22° C., the server transmits a target temperature value of 22° C. as a representative setting value to the air conditioner. 
     After the air conditioner receives the representative setting value, when power is supplied to the air conditioner, the controller provided at the air conditioner sets a target temperature value of the air conditioner to 22° C. automatically. The user may set the air conditioner to a specific temperature only by applying power to the air conditioner. 
     Here, the representative setting value may be different from the setting value transmitted from the electronic device to the server. For example, even when the air conditioner transmits a target temperature of 23° C. a predetermined number of times or more to the server, the representative setting value may be 22° C. That is, the representative setting value may not be a value reflecting the device usage pattern of the user as it is, but may be a value reflecting all the usage patterns of electronic devices classified into the same cluster as the electronic device of the user. In this manner, the present disclosure does not simply control the electronic device according to the usage pattern of the user, but a setting value commonly preferred by users having a tendency similar to that of the user is reflected at the electronic device. 
     Meanwhile, the present disclosure may further include re-confirming intention of a user even when the electronic device  120  is classified into a specific cluster. 
       FIG. 5  is a conceptual diagram illustrating one embodiment in which a server reclassifies a cluster of a specific electronic device. 
     Referring to  FIG. 5 , the server classifies the electronic device into a specific cluster based on the setting value received from the electronic device (S 410  to S 450 ). Then, when the electronic device is activated (S 460 ), the controller provided at the electronic device  120  may control the output unit so that at least one of the classified cluster data received from the server  140  and a representative setting value corresponding to the classified cluster data is displayed. In addition, the controller provided at the electronic device  120  may output a message confirming whether the representative setting value received from the server  140  is set as a default setting value. 
     Then, the controller provided at the electronic device  120  determines whether the representative setting value is set as the default setting value based on a user input with respect to the message. In detail, when the user makes a positive selection with respect to the message, the controller provided at the electronic device  120  controls the electronic device  120  to be set to the representative setting value whenever the electronic device  120  is activated. On the other hand, when the user makes a negative selection with respect to the message, the controller provided at the electronic device  120  transmits a request of cluster reclassification to the server  140 . 
     When the server  140  receives the cluster reclassification request, the server  140  performs the steps S 410  to S 440  again to reclassify the cluster of the electronic device  120 . In this manner, the present disclosure may not reflect the representative setting value of a specific cluster unconditionally to the electronic device, but may reflect intention of the user in setting the default setting value of the electronic device. 
     Meanwhile, when the electronic device is classified into a specific cluster, the present disclosure may generate a shortcut menu that allows the electronic device to be quickly set to a setting value representing a particular cluster. 
       FIG. 6  is a conceptual diagram illustrating one embodiment of generating a shortcut menu for allowing an electronic device to be quickly set to a set value representing a cluster into which the electronic device is classified. 
     Referring to  FIG. 6 , the server classifies the electronic device into a specific cluster based on the setting value received from the electronic device (S 510  to S 550 ). Then, when the electronic device is activated (S 560 ), the controller provided at the electronic device  120  may control the output unit so that at least one of the classified cluster data received from the server  140  and a representative setting value corresponding to the classified cluster data is displayed. In addition, the controller provided at the electronic device  120  may output a message confirming whether to generate a shortcut menu. 
     Here, the shortcut menu may be a menu for setting the representative setting value as a setting value of the electronic device  120 . A user may allow the electronic device  120  to reflect the representative setting value only by selecting the shortcut menu. 
     Then, the controller provided at the electronic device  120  determines whether to generate the shortcut menu based on a user input with respect to the message. In detail, when the user makes a positive selection with respect to the message, the controller provided at the electronic device  120  generates the shortcut menu at the output unit, and the electronic device  120  is set to the representative setting value whenever a user input is applied to the shortcut menu. On the other hand, when the user makes a negative selection with respect to the message, the controller provided at the electronic device  120  transmits a request of cluster reclassification to the server. 
     In this manner, the present disclosure allows a setting value representing users having a usage pattern similar to the electronic device usage pattern of the user to be immediately reflected to the electronic device. According to the present disclosure, after the electronic device is activated, the user may set the electronic device to the representative setting value with only one user input. 
     Meanwhile, after the electronic device is classified into a specific cluster, when the electronic device usage pattern of the user is changed, the electronic device may be classified into a new cluster. 
       FIG. 7  is a conceptual diagram illustrating one embodiment in which a server reclassifies a cluster of an electronic device according to the present disclosure. 
     The present disclosure may include, after the electronic device  120  is set to the representative setting value (S 620 ), receiving a new user input by the electronic device  120  (S 630 ), when the new user input satisfies a predetermined condition, transmitting a changed setting value to the server  140  by the electronic device (S 640 ), and when the changed setting value is received a predetermined number of times or more from the electronic device (S 650 ), reclassifying the electronic device into another one of a plurality of clusters by the server (S 660 ). In detail, referring to  FIG. 7 , when the electronic device receives classified cluster data and a representative setting value corresponding to the classified cluster data from the server, a controller provided at the electronic device may set the electronic device to the representative setting value whenever the electronic device is activated. 
     In one embodiment, a predetermined condition may be that the electronic device  120  receives a new user input within a predetermined time from a point of time when the electronic device  120  is set to the representative setting value. 
     In another embodiment, the predetermined condition may be a case that a similarity between the changed setting value and a representative setting value corresponding to a cluster different from a cluster to which the electronic device belongs is greater than a similarity between the changed setting value by the new user input and the representative setting value corresponding to the cluster to which the electronic device  120  belongs. 
     The controller provided at the electronic device  120  transmits the changed setting value to the server  140  whenever a user input that satisfies the predetermined condition is applied. When the changed setting value is received a predetermined number of times or more from the electronic device, the server  140  determines that a usage pattern of the electronic device  120  has changed, and reclassifies the cluster of the electronic device  120  based on the changed setting value. Then, the server  140  transmits redetermined cluster data and a representative setting value corresponding to the redetermined cluster data to the electronic device  120 . 
     When the electronic device  120  receives the redetermined cluster data and the representative setting value corresponding to the redetermined cluster data, the controller provided at the electronic device  120  sets the electronic device to the representative setting value corresponding to the redetermined cluster data whenever the electronic device  120  is activated. 
     In this manner, when the usage pattern of a user of an electronic device is changed, the present disclosure reclassifies the electronic device into a new cluster regardless of intention of the user, and enables the electronic device to be quickly set to a representative setting value of the reclassified cluster. 
     Meanwhile, the present disclosure enables the user to quickly set the electronic device by using the cluster data formed by the method described in  FIG. 2 . 
       FIG. 8  is a conceptual diagram illustrating one embodiment in which an electronic device displays cluster data. 
     The present disclosure may further include transmitting representative setting values corresponding to a plurality of clusters, respectively, to the electronic device by the server, when the electronic device receives the representative setting value corresponding to each of the plurality of clusters, displaying the representative setting values, receiving selection of any one representative setting value among the displayed representative setting values by the electronic device, and setting the any one electronic device to the selected representative setting value whenever the electronic device is activated. 
       FIG. 8  is screen information displayed at an output unit of an air conditioner. Referring to  FIG. 8 , a plurality of representative setting values received from the server may be displayed at the output unit of the air conditioner. In addition, an indicator indicating a cluster corresponding to each of the representative setting values may be displayed at the output unit. The indicator enables intuitive recognition of characteristics of each of a plurality of clusters. 
     In one embodiment, as shown in  FIG. 8 , the output unit of the air conditioner may display a representative setting value of a cluster (“air conditioner cooling group”) that sets a relatively low target temperature, a representative setting value of a cluster (“air conditioner auto group”) that sets a target temperature flexibly according to a current temperature, and a representative setting value of a cluster (“air conditioner saving group”) that sets a relatively high target temperature. In addition, a menu capable of customizing the air conditioner settings may be displayed at the output unit. 
     A controller provided at the electronic device may set a default setting value of the electronic device based on a user input to the output unit. 
     In one embodiment, when a representative setting value of 28° C. among the representative setting values shown in  FIG. 8  is selected, the controller provided at the air conditioner sets the target temperature of the air conditioner to 28° C. whenever the air conditioner is activated. 
     In this manner, the present disclosure enables a user to easily set the electronic device by guiding a setting value preferred by a plurality of users. 
     The present disclosure can be implemented as computer-readable codes in a program-recorded medium. The computer-readable medium may include all types of recording devices each storing data readable by a computer system. Examples of such computer-readable media may include hard disk drive (HDD), solid state disk (SSD), silicon disk drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage element and the like. Also, the computer-readable medium may also be implemented as a format of carrier wave (e.g., transmission via an Internet). The computer may include the controller  180  of the terminal. The above detailed description should not be limitedly construed in all aspects and should be considered as illustrative. The scope of the present disclosure should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present disclosure are included in the scope of the present disclosure.
