DETAILED DESCRIPTION
Various embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. The term “or” is used herein in both the alternative and conjunctive sense, unless otherwise indicated. The terms “illustrative” and “exemplary” are used to be examples with no indication of quality level. Like numbers refer to like elements throughout. Moreover, while certain embodiments of the present invention are described with reference to prediction data analysis, one of ordinary skill in the art will recognize that the disclosed concepts can be used to perform other types of data analysis.
I. OVERVIEW
Various embodiments of the present invention make important technical contributions to efficiently and reliably perform multi-event-type prediction data analysis (e.g., multi-disease first-occurrence prediction data analysis) by introducing techniques for performing multi-event-type prediction data analysis using a single multi-event-type prediction model, rather than multiple per-event-type prediction models. Performing multi-event-type prediction data analysis using a single multi-event-type prediction model rather than multiple per-event-type prediction models is technologically advantageous for at least the following reasons: (1) training a single multi-event-type prediction model requires one training session while training multiple per-event-type prediction models requires multiple training sessions; thus, performing multi-event-type prediction data analysis using a single multi-event-type prediction model reduces computational costs of training machine learning frameworks used to perform multi-event-type prediction data analysis; and (2) once trained, a single trained multi-event-type prediction model typically has less parameter/hyper-parameter data than multiple trained per-event-type prediction models; thus, performing multi-event-type prediction data analysis using a single multi-event-type prediction models reduces storage complexity associated with storing parameter/hyper-parameter data of machine learning frameworks used to perform multi-event-type prediction data analysis. Accordingly, by disclosing techniques for efficiently and reliably performing multi-event-type prediction data analysis via performing multi-event-type prediction data analysis using a single multi-event-type prediction model, various embodiments of the present invention increase efficiency (including training efficiency and storage efficiency) and reliability of performing multi-event-type prediction data analysis.
Moreover, various embodiments of the present invention provide efficient and reliable techniques for integrating event incidence rate data during training of multi-event-types machine learning models. For example, various embodiments of the present invention introduce techniques for adjusting per-event-type loss values based on incidence rate penalty weight values for event types, where the incidence rate penalty weight values may be inversely proportional to incidence rates of event types. In some embodiments, the incidence rate penalty weight values are determined to penalize deviations between ground-truth event labels and inferred event probability values for less frequent event types relative to deviations between ground-truth event labels and inferred event probability values for more frequent event types. By utilizing incidence rate penalty weight values, various embodiments of the present invention provide efficient and reliable techniques for integrating event incidence rate data during training of multi-event-types machine learning models, which in turn enables more efficient and more reliable predictions on rare event types (e.g., rare diseases). In doing so, various embodiments of the present invention substantially advance the field of prediction data analysis and make important technical contributions to improving the effectiveness and accuracy of various existing multi-event-type prediction systems, e.g., various existing multi-disease prediction systems.
II. DEFINITIONS
The term “training data field” describes a data object that describes one or more input properties of a predictive entity along with one or more ground-truth event labels for the predictive entity, where each ground-truth event label for the predictive entity may describe whether the predictive entity is recorded to have experienced first-occurrence of a corresponding event type, repeat-occurrence of the corresponding event type, or no-occurrence of a corresponding event type. For example, a particular training data field may describe one or more properties of a patient predictive entity (e.g., medical visit history of the patient predictive entity, demographic information of the patient predictive entity, medical claim history of the patient predictive entity, prescription claim history and/or the like) along one or more ground-truth event labels each describing whether the patient predictive entity has experienced first occurrence of a corresponding disease during a specified prospective timeframe, repeat-occurrence of the corresponding disease during the specified prospective timeframe, or no-occurrence of the corresponding disease during the specified prospective timeframe. A training data field may include a training input set and an event label set, as described below.
The term “training input set” describes a data object that describes one or more input properties of a predictive entity as indicated by a corresponding training data field. The format of the training input set may be defined in accordance with an input structure of a machine learning model configured to be trained using the corresponding training data field, such as a multi-event-type prediction machine learning model. Examples of training input sets include collections of input values that describe at least one of medical visit histories of corresponding patient predictive entities, demographic information of corresponding patient predictive entities, and medical claim histories of corresponding patient predictive entities.
The term “event label set” describes a data object that describes one or more ground-truth event labels for a corresponding predictive entity as indicated by a corresponding training data field, where each ground-truth event label for the predictive entity describes whether the predictive entity is recorded to have experienced first-occurrence of a corresponding event type, repeat-occurrence of the corresponding event type, or no-occurrence of a corresponding event type. Examples of event label sets include collection of ground-truth values that describe whether corresponding patient predictive entities have experienced first-occurrences of particular diseases during specified prospective timeframes, repeat-occurrences of particular diseases during specified prospective timeframes, and no-occurrences of particular diseases during particular specified prospective timeframes.
The term “inferred event probability set” describes a data object that describes one or more inferred event probability values for a corresponding training data field, where the inferred event probability values include an inferred event probability value for each ground-truth event label described by the corresponding training data field, and where the inferred event probability values are determined by processing the training input sets associated with corresponding training data fields using a multi-event-type prediction model. For example, given a training data field that describes ground-truth event labels for two diseases, the inferred event probability set for the training data field may include an inferred event probability value for each of the two diseases.
The term “multi-event-type type prediction model” describes a data object that describes parameters and/or hyper-parameters of a machine learning framework that is configured to process input data associated with a predictive entity to determine two or more inferred event probabilities for the predictive entity, where the two or more inferred event probabilities include an inferred event probability for each respective event type of two or more event types. For example, a multi-event-type prediction model may describe a machine learning framework that is configured to process real-time patient data (e.g., patient visit history data, patient claim history data, patient demographic data, and/or the like) to generate first-occurrence probabilities for two or more disease types associated with the multi-event-type prediction model.
The term “per-event-type loss value” describes a data object that describes an overall deviation measure of: (i) inferred event probability values generated by a multi-prediction event prediction model in accordance with a group of training data fields associated with a corresponding event type, and (ii) ground-truth event labels for the group of training data fields that are associated with the corresponding event type, where the group of training data fields include training data fields that describe no-occurrence of the corresponding event type or first-occurrence of the corresponding event type, but not repeat-occurrence of the corresponding event type. For example, given two event types E1 and E2, and given two training data fields T1 and T2, if T1 has an inferred probability value of P1 for E1 and an inferred probability value of P2 for E2, and further if T2 has an inferred probability value of P3 for E1 and inferred probability value of P4 for E2, and further if T1 has a ground-truth event label of 2 denoting repeat-occurrence with respect to E1 and a ground-truth event label of 0 denoting no-occurrence with respect to E2, and further if T2 has a ground-truth event label of 1 denoting first-occurrence with respect to E1 and a ground-truth event label of 0 denoting no-occurrence with respect to E2, then: (i) the per-event-type loss value for E1 may be determined based at least in part on the deviation measure between P3 and 1 and (ii) the per-event-type loss value for E2 may be determined based at least in part on a deviation measure between P2 and 0 and a deviation measure between P4 and 0. In some embodiments, a per-event-type loss value for an event type is a binary cross-entropy loss value determined based at least in part on the above-described overall deviation measure associated with the particular event type.
The term “cross-event-type loss value” describes a data object that describes an overall loss value for a multi-event-type prediction model across the two or more event types associated with the multi-event-type prediction model, where the overall loss value is determined based at least in part on each per-event-type loss value associated with an event type of the one or more event types. In some embodiments, the cross-event-type loss value for the two or more event types is determined based at least in part on a raw summation of each per-event-type loss value associated with an event type of the one or more event types. In some embodiments, the cross-event-type loss value for the two or more event types is determined based at least in part on a weighted summation of each per-event-type loss value associated with an event type of the one or more event types, where the pre-summation adjustment of a per-event-type loss value is determined based at least in part on at least one of the number of training data fields used to determine the per-event-type loss values and an incidence rate penalty weights for the event types associated with the per-event-type loss values.
The term “incidence rate penalty weight value” is a data object that describes a desired level of magnification in the per-event-type loss value for a corresponding event type before using the per-event-type loss value along with the per-event-type loss values for other event types in order to generate a cross-event-type loss value, where the desired level of magnification is determined in a manner that has an inverse relationship with an overall incidence rate (e.g., an observed overall incidence rate, an assumed overall incidence rate, and/or the like) of the event type among a population of predictive entities. Accordingly, the incidence rate penalty weight values may be determined in a manner configured to penalize deviations between ground-truth event labels and inferred event probability values for less frequent event types relative to more frequent event types.

V. EXEMPLARY SYSTEM OPERATIONS
FIG. 4 is a flowchart diagram of an example process 400 for generating a first occurrence prediction for a prediction input set in relation to a plurality of event types. Via the various steps/operations of the process 400, the prediction data analysis computing entity 106 can efficiently and reliably perform multi-event-type prediction using a single multi-event-type prediction model associated with a plurality of event types instead of multiple per-event-type prediction models, which in turn reduces the computational complexity of training machine learning frameworks configured to perform multi-event-type prediction as well as the storage complexity of storing parameter/hyper-parameter data of machine learning frameworks configured to perform multi-event-type prediction.
The process 400 begins at step/operation 401 when the prediction data analysis computing entity 106 identifies a plurality of training data fields. A training data field is a data object that describes one or more input properties of a predictive entity along with one or more ground-truth event labels for the predictive entity, where each ground-truth event label for the predictive entity may describe whether the predictive entity is recorded to have experienced first-occurrence of a corresponding event type, repeat-occurrence of the corresponding event type, or no-occurrence of a corresponding event type. For example, a particular training data field may describe one or more properties of a patient predictive entity (e.g., medical visit history of the patient predictive entity, demographic information of the patient predictive entity, medical claim history of the patient predictive entity, and/or the like) along one or more ground-truth event labels each describing whether the patient predictive entity has experienced first occurrence of a corresponding disease during a specified prospective timeframe, repeat-occurrence of the corresponding disease during the specified prospective timeframe, or no-occurrence of the corresponding disease during the specified prospective timeframe. A training data field may include a training input set and an event label set, as described below.
In some embodiments, each training data field includes a training input set. The training input set is a data object that describes one or more input properties of a predictive entity as indicated by a corresponding training data field. The format of the training input set may be defined in accordance with an input structure of a machine learning model configured to be trained using the corresponding training data field, such as a multi-event-type prediction machine learning model. Examples of training input sets include collections of input values that describe at least one of medical visit histories of corresponding patient predictive entities, demographic information of corresponding patient predictive entities, and medical claim histories of corresponding patient predictive entities.
In some embodiments, each training data field includes an event label set. The event label set is a data object that describes one or more ground-truth event labels for a corresponding predictive entity as indicated by a corresponding training data field, where each ground-truth event label for the predictive entity describes whether the predictive entity is recorded to have experienced first-occurrence of a corresponding event type, repeat-occurrence of the corresponding event type, or no-occurrence of a corresponding event type. Examples of event label sets include collection of ground-truth values that describe whether corresponding patient predictive entities have experienced first-occurrences of particular diseases during specified prospective timeframes, repeat-occurrences of particular diseases during specified prospective timeframes, and no-occurrences of particular diseases during particular specified prospective timeframes.
An operational example of training data fields 501-502 is presented in FIG. 5. As depicted in FIG. 5, each depicted training data field is associated with a prediction metadata set 511, a training input set 512, and an event label set 513. The prediction metadata set 511 includes a member identifier 521 and a prediction date descriptor 522. The member identifier 521 for a training data field describes a member predictive entity that is associated with the training data field. The prediction date descriptor 522 for a training data field describes a presumed prediction date according to which a retrospective timeframe for the training data field and a prospective timeframe for the training data field are inferred, as further defined below.
A retrospective timeframe is a data object that describes a predefined period of time before a presumed prediction date associated with a corresponding training data field, while a prospective timeframe is a data object that describes a predefined period of time after a presumed prediction date associated with a corresponding training data field. In the operational example of FIG. 5, the retrospective timeframe for a respective training data field includes the time period starting at twenty-four months prior to the presumed prediction date for the respective training data field as described by prediction date descriptor 522 for the training data field and continuing until the noted presumed prediction date. Moreover, the prospective timeframe for a respective training data field includes the time period starting at the presumed prediction date for the training data field as described by prediction date descriptor 522 for the respective training data field and continuing until n months after the presumed prediction date (where the prediction time window can be n number of months, where the value of n can be fine-tuned for a given application).
As further depicted in FIG. 5, the training input set 512 includes a historical visit subject descriptor 531, a historical visit time descriptor 532, an age descriptor 533, and a gender descriptor 534. The historical visit subject descriptor 531 for a respective training data field is a vector that includes a collection of each medical code list for a medical visit of the member identifier 521 associated with the training data field that falls within the retrospective timeframe, where the collection describes the medical code lists for the medical visits in accordance a particular medical visit order (e.g., a temporal medical visit order, a cross-temporal medical visit order, a duration-wise medical visit order, and/or the like), and where each medical code list for a medical visit describes a zero-padded list of the medical codes (e.g., diagnosis codes such as International Statistical Classification of Diseases and Related Health Problems (ICD) codes, drug codes such as National Drug Codes (NDCs), and lab result codes) associated with the medical visit. The historical visit time descriptor 532 for a respective training data field is a vector that describes a collection of each temporally-encoded floating point value for a medical visit of the member identifier 521 associated with the training data field that falls within the retrospective timeframe, where the collection describes the temporally-encoded floating point values for the medical visits in accordance the particular medical visit order of the historical visit subject descriptor 531, and where each temporally-encoded floating point value for a medical visit describes a relative oldness of a visit date associated with the medical visit as a floating point value. The age descriptor 533 for a training data field describes a recorded age of the member identifier 521 associated with the training data field as of the presumed prediction date for the training data field, while the gender descriptor 534 for a training data field describes a recorded gender of the member identifier 521 associated with the training data field as of the presumed prediction date for the training data field.
As further depicted in FIG. 5, the event label set 513 for a training data field includes two per-event-type event labels: a diabetes event label 541 and a kidney-failure event label 542. Each per-event-type event label for a corresponding training data field describes whether a corresponding event type (i.e., the diabetes event type for the diabetes event label 541 and the kidney-failure event type for the kidney-failure event label 542) has occurred in neither the retrospective timeframe for the corresponding training data field nor the prospective timeframe for the corresponding training data field and thus describes no-occurrence of the corresponding event type, or the corresponding event type has not occurred in the retrospective timeframe for the corresponding training data field but has occurred in the prospective timeframe for the corresponding training data field and thus describes first-occurrence of the corresponding event type, or the corresponding event type has occurred in the retrospective timeframe for the corresponding training data field and thus describes repeat-occurrence of the corresponding event type.
In particular, as depicted in the training data field 501 of FIG. 5, the member identifier 12345 has a value of one for the diabetes event label 541 describing first-occurrence for the diabetes event type and a value of zero for the kidney-failure event label 542 describing no-occurrence of the kidney-failure event type. This means that the member identifier 12345 has not experienced diabetes in the retrospective timeframe for the training data field 501 (i.e., May 13, 2014 to May 13, 2016) but has experienced diabetes in the prospective timeframe for the training data field 501 (i.e., May 13, 2016 to Aug. 13, 2016). This further means that the member identifier 12345 has not experienced diabetes in either the retrospective timeframe for the training data field 501 or the prospective timeframe for the training data field 501.
Moreover, as depicted in the training data field 502 of FIG. 5, the member identifier 12345 has a value of two for the diabetes event label 541 describing repeat-occurrence for the kidney-failure event type and a value of one for the kidney-failure event label 542 describing no-occurrence of the kidney-failure event type. This means that the member identifier 12345 has experienced diabetes in the retrospective timeframe for the training data field 502 (i.e., Aug. 19, 2015 to Aug. 19, 2017). This further means that the member identifier 12345 has not experienced kidney-failure in the retrospective timeframe for the training data field 501 but has experienced kidney-failure in the prospective timeframe of the training data field 502 (i.e., Aug. 19, 2017 to Nov. 19, 2017).
Returning to FIG. 4, at step/operation 402, the prediction data analysis computing entity 106 processes the plurality of training data fields using the multi-event-type prediction model to generate an inferred event probability set for each training data field of the plurality of training data fields. The inferred event probability set is a data object that describes one or more inferred event probability values for a corresponding training data field, where the inferred event probability values include an inferred event probability value for each ground-truth event label described by the corresponding training data field, and where the inferred event probability values are determined by processing the training input set associated with the corresponding training data field using a multi-event-type prediction model. For example, given a training data field that describes ground-truth event labels for two diseases, the inferred event probability set for the training data field may include an inferred event probability value for each of the two diseases.
The multi-event-type type prediction model is a data object that describes parameters and/or hyper-parameters of a machine learning framework that is configured to process input data associated with a predictive entity to determine two or more inferred event probabilities for the predictive entity, where the two or more inferred event probabilities include an inferred event probability for a respective event type. For example, a multi-event-type prediction model may describe a machine learning framework that is configured to process real-time patient data (e.g., patient visit history data, patient claim history data, patient demographic data, and/or the like) to generate first-occurrence probabilities for two or more disease types associated with the multi-event-type prediction model.
An operational example of an event probability inference data object 600 is depicted in FIG. 6. As depicted in FIG. 6, the event probability inference data object 600 includes six non-header rows each associated with a training data field. The first two columns of the event probability inference data object 600 describe per-event-type event labels for a diabetes event type and a kidney failure event type.
In particular, column 601 of the event probability inference data object 600 of FIG. 6 describes the per-event-type event label for the diabetes event type, while column 602 describes the per-event-type event label for the kidney-failure event type. Accordingly, as depicted in FIG. 6, the training data field corresponding to the first non-header row 611 describes no-occurrence of a corresponding predictive entity with respect to the diabetes event type and first-occurrence of a corresponding predictive entity with respect to the kidney-failure event type; the training data field corresponding to the second non-header row 612 describes repeat-occurrence of a corresponding predictive entity with respect to the diabetes event type and first-occurrence of a corresponding predictive entity with respect to the kidney-failure event type; the training data field corresponding to the third non-header row 613 describes first-occurrence of a corresponding predictive entity with respect to the diabetes event type and no-occurrence of a corresponding predictive entity with respect to the kidney-failure event type; the training data field corresponding to the fourth non-header row 614 describes first-occurrence of a corresponding predictive entity with respect to the diabetes event type and repeat-occurrence of a corresponding predictive entity with respect to the kidney-failure event type; the training data field corresponding to the fifth non-header row 615 describes no-occurrence of a corresponding predictive entity with respect to the diabetes event type and first-occurrence of a corresponding predictive entity with respect to the kidney-failure event type; and the training data field corresponding to the sixth non-header row 616 describes repeat-occurrence of a corresponding predictive entity with respect to the diabetes event type and first-occurrence of a corresponding predictive entity with respect to the kidney-failure event type.
As further depicted in FIG. 6, the latter two columns of the event probability inference data object 600 describe inferred event probability values for the diabetes event type and the kidney failure event type. In particular, column 603 describes the per-event-type inferred event probability values for the diabetes event type, while column 604 describes the per-event-type inferred event probability values for the kidney-failure event type.
Accordingly, as depicted in FIG. 6, the first non-header row 611 is associated with a diabetes-related inferred event probability value of 0.65432 and a kidney-failure-related inferred event probability value of 0.74396; the second non-header row 612 is associated with a diabetes-related inferred event probability value of 0.11892 and a kidney-failure-related inferred event probability value of 0.07834; the third non-header row 613 is associated with a diabetes-related inferred event probability value of 0.25678 and a kidney-failure-related inferred event probability value of 0.15672; the fourth non-header row 614 is associated with a diabetes-related inferred event probability value of 0.38729 and a kidney-failure-related inferred event probability value of 0.61982; the fifth non-header row 615 is associated with a diabetes-related inferred event probability value of 0.78923 and a kidney-failure-related inferred event probability value of 0.61982; and the sixth non-header row 616 is associated with a diabetes-related inferred event probability value of 0.89102 and a kidney-failure-related inferred event probability value of 0.77213.
Returning to FIG. 4, at step/operation 403, the prediction data analysis computing entity 106 generates a per-event-type loss value for each event type of the plurality of event types. A per-event-type loss value is a data object that describes an overall deviation measure of: (i) inferred event probability values generated by a multi-prediction event prediction model in accordance with a group of training data fields associated with a corresponding event type, and (ii) ground-truth event labels for the group of training data fields that are associated with the corresponding event type, where the group of training data fields include training data fields that describe no-occurrence of the corresponding event type or first-occurrence of the corresponding event type, but not repeat-occurrence of the corresponding event type.
For example, given two event types E1 and E2, and given two training data fields T1 and T2, if T1 has an inferred probability value of P1 for E1 and an inferred probability value of P2 for E2, and further if T2 has an inferred probability value of P3 for E1 and inferred probability value of P4 for E2, and further if T1 has a ground-truth event label of 2 denoting repeat-occurrence with respect to E1 and a ground-truth event label of 0 denoting no-occurrence with respect to E2, and further if T2 has a ground-truth event label of 1 denoting first-occurrence with respect to E1 and a ground-truth event label of 0 denoting no-occurrence with respect to E2, then: (i) the per-event-type loss value for E1 may be determined by the deviation measure between P3 and 1; and (ii) the per-event-type loss value for E2 may be determined by a weighted average of the deviation measure between P2 and 0 and a deviation measure between P4 and 0. In some embodiments, a per-event-type loss value for an event type is a binary cross-entropy loss value determined based at least in part on the above-described overall deviation measure associated with the particular event type.
In some embodiments, step/operation 403 may be performed in relation to an event type in accordance with the process depicted in FIG. 7. The process depicted in FIG. 7 begins at step/operation 701 when the prediction data analysis computing entity 106 determines a related subset of the plurality of training data fields for the event type. In some embodiments, a training data field is in the related subset for the event type if the event label set for the training data field describes that the training data field describes no-occurrence of the event type in relation to the training data field or first-occurrence of the event type in relation to the training data field.
In some embodiments, to determine the related subset for an event type, the prediction data analysis computing entity 106 excludes/filters all training data fields that describe repeat-occurrence of the event type. In some embodiments, each event label of the plurality of event labels for a training data field of the plurality of training data fields describes no-occurrence of the event type associated with the event label if neither the retrospective timeframe for the training data field nor the prospective timeframe for the training data field describes ground-truth occurrence of the event type. In some embodiments, each event label of the plurality of event labels for a training data field of the plurality of training data fields describes first-occurrence of the event type associated with the event label if only the prospective timeframe for the training data field describes ground-truth occurrence of the event type. In some embodiments, each event label of the plurality of event labels for a training data field of the plurality of training data fields describes repeat-occurrence of the event type associated with the event label if both the retrospective timeframe for the training data field and the prospective timeframe for the training data field describe ground-truth occurrence of the event type.
In some embodiments, determining the related subset for an event type of the plurality of event types comprises: for each training data field of the plurality of training data fields, determining a related event label of the plurality of event labels for the training data field that is associated with the event type; and excluding from the plurality of training data fields any training data field whose related event label describes repeat-occurrence of the event type in relation to the training data field. In some embodiments, each event label set for a training field of the plurality of training fields comprises a plurality of event labels for the training data field, each event label of the plurality of event labels for a training data field of the plurality of training data fields is associated with an event type of the plurality of event types, and each event label of the plurality of event labels for a training data field of the plurality of training data fields describes one of no-occurrence of the event type associated with the event label in relation to the training data field, first-occurrence of the event type associated with the event label in relation to the training data field, and repeat-occurrence of the event type associated with the event label in relation to the training data field.
An operational example of two per-event-type filtered data objects 801-802 that each describe related training data fields for a related event type is depicted in FIG. 8. As depicted in FIG. 8, the per-event-type filtered data object 801 for the diabetes event type includes information from the first non-header row 611, the third non-header row 613, the fourth non-header row 614, and the fifth non-header row 615 of the event probability inference data object 600 of FIG. 5, because the remaining non-header rows of the event probability inference data object 600 (i.e., the second non-header row 612 and the sixth non-header row 615) describe repeat-occurrence of the diabetes event type.
As further depicted in FIG. 8, the per-event-type filtered data object 802 for the kidney-failure event type includes information from the first non-header row 611, the second non-header row 612, the third non-header row 613, the fifth non-header row 615, and the sixth non-header row 616 of the event probability inference data object 600 of FIG. 5, because the remaining non-header rows of the event probability inference data object 600 (i.e., the fourth non-header row 614) describe repeat-occurrence of the kidney-failure event type.
Returning to FIG. 7, at step/operation 702, the prediction data analysis computing entity 106 generates an overall deviation measure for the related subset associated with the event type. The overall deviation measure may be determined by combining each per-data-field deviation measure for a training data field in the related subset, where the per-data-field deviation measure for a training data field in the related subset may be determined based at least in part on a deviation measure (e.g., a squared deviation measure) of the ground-truth event label for the training data field and the inferred event probability value for the training data field. For example, the overall deviation measure for the event type may be determined by summing each per-data-field deviation measure for a training data field in the related subset, where the per-data-field deviation measure for a training data field in the related subset may be determined based at least in part on a squared deviation measure of the ground-truth event label for the training data field and the inferred event probability value for the training data field.
At step/operation 703, the prediction data analysis computing entity 106 generates the per-event-type loss value for the event type based at least in part on the overall deviation measure for the event type. In some embodiments, the prediction data analysis computing entity 106 adopts the overall deviation measure for the event type as the per-event-type loss value for the event type. In some embodiments, the prediction data analysis computing entity 106 generates a binary cross-entropy loss value for the event type based at least in part on the overall deviation measure for the event type. In some embodiments, the prediction data analysis computing entity 106 processes the overall deviation measure for the event type using one or more defined operations (e.g., using a trained machine learning model, such as a trained neural network model) to generate the per-event-type for the event type.
Returning to FIG. 4, at step/operation 404, the prediction data analysis computing entity 106 determines a cross-event-type loss value for the plurality of event types based at least in part on each per-event-type loss value for an event type of the plurality of event types. The cross-event-type loss value is a data object that describes an overall loss value for a multi-event-type prediction model across the two or more event types associated with the multi-event-type prediction model, where the overall loss value is determined based at least in part on each per-event-type loss value associated with an event type of the one or more event types. In some embodiments, the cross-event-type loss value for the two or more event types is determined based at least in part on a raw summation of each per-event-type loss value associated with an event type of the one or more event types. In some embodiments, the cross-event-type loss value for the two or more event types is determined based at least in part on an adjusted summation of each per-event-type loss value associated with an event type of the one or more event types, where the pre-summation adjustment of a per-event-type loss value is determined based at least in part on at least one of the number of training data fields used to determine the per-event-type loss value and an incidence rate penalty weight for the event type associated with the per-event-type loss value.
In some embodiments, determining the cross-event-type loss value comprises, for each event type of the plurality of event types, determining an adjusted loss value based at least in part on the per-event-type loss value for the event type and a field count of the related subset associated with the event type; determining a combined loss value based at least in part on each adjusted loss value for an event type of the plurality of event types; determining a loss normalization factor based at least in part on each field count for an event type of the plurality of event types; determining a normalized loss value based at least in part on the combined loss value and the loss normalization factor; and determining the cross-event-type loss value based at least in part on the normalized loss value. In some of the noted embodiments, determining each adjusted loss value for an event type of the plurality of event types comprises determining an incidence rate penalty weight for the event type based at least in part on an overall incidence rate of the event type; and determining the adjusted loss value for the event type based at least in part on the per-event-type loss value for the event type, the field count of the related subset for the event type, and the incidence rate penalty weight for the event type.
In some embodiments, step/operation 404 may be performed in accordance with the process depicted in FIG. 9. The process depicted in FIG. 9 begins at step/operation 901 when the prediction data analysis computing entity 106 determines an adjusted loss value for each event type of the plurality of event types based at least in part on the per-event-type type for the event type and the field count of the related subset of the plurality of training data fields associated with the event type (i.e., the number of training data fields in the subset of the plurality of training data fields that was used to determine the per-event-type type for the event type). In some embodiments, to generate the adjusted loss value for an event type, the prediction data analysis computing entity 106 multiplies the per-event-type type for the event type and the field count for the noted event type.
For example, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 multiplies Loss1, which is the per-event-type loss value for the diabetes event type, by 4, which is the number of fields of the per-event-type filtered data object 801 that is associated with the diabetes event type, to generate the adjusted loss value for the diabetes event type. Moreover, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 multiplies Loss2, which is the per-event-type loss value for the kidney-failure event type, by 5, which is the number of fields of the per-event-type filtered data object 802 that is associated with the kidney-failure event type, to generate the adjusted loss value for the kidney-failure event type.
At step/operation 902, the prediction data analysis computing entity 106 determines a combined loss value based at least in part on each adjusted loss value for an event type of the plurality of event types. In some embodiments, subsequent to determining each adjusted loss value for an event type of the plurality of event types based at least in part on the per-event-type type for the event type and the field count of the related subset of the plurality of training data fields associated with the event type, the prediction data analysis computing entity 901 combines (e.g., sums up) the determined adjusted loss values to determine the combined loss value. For example, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 sums up the adjusted loss value for the diabetes event type (i.e. Loss1*4) and the adjusted loss value for the kidney-failure event type (i.e., Loss2*5) to determine the combined loss value for both the diabetes event type and the kidney-failure event type.
At step/operation 903, the prediction data analysis computing entity 106 determines a loss normalization factor based at least in part on each field count for an event type of the plurality of event types. As noted above, the field count of an event type is a data object that describes the number of training data fields in the subset of the plurality of training data fields that was used to determine the per-event-type type for the event type. In some embodiments, subsequent to determining each field count for an event type of the plurality of event types, the prediction data analysis computing entity 106 determines the loss normalization factor by combining (e.g., summing up) each field count for an event type of the plurality of event types. For example, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 sums up the field count for the diabetes event type (i.e., 4) with the field count for the kidney-failure event type (i.e., 5) to determine the loss normalization factor.
At step/operation 904, the prediction data analysis computing entity 106 determines a normalized loss value based at least in part on the combined loss value and the loss normalization factor. In some embodiments, subsequent to determining the combined loss value and the loss normalization factor, the prediction data analysis computing entity 106 determines the normalized loss value based at least in part on the combined loss value and the loss normalization factor. For example, as depicted in FIG. 10, the prediction data analysis computing entity 106 may divide the combined loss value (i.e., Loss1*4+Loss2*5) by the loss normalization factor (i.e., 4+5) to determine the normalized loss value.
At step/operation 905, the prediction data analysis computing entity 106 determines the cross-event-type loss value based at least in part on the normalized loss value. In some embodiments, subsequent to determining the normalized loss value, the prediction data analysis computing entity 106 adopts the normalized loss value as the cross-event-type loss value. In some embodiments, the prediction data analysis computing entity 106 performs one or more adjustment operations (e.g., in accordance with a trained loss aggregation model) to the normalized loss value to generate the cross-event-type loss value.
In some embodiments, step/operation 404 may be performed in accordance with the process depicted in FIG. 11. The process depicted in FIG. 11 begins at step/operation 1101 when the prediction data analysis computing entity 106 determines an adjustment value for each event type of the plurality of event types based at least in part on the field count for the event type and an incidence rate penalty weight for the event type. In some embodiments, to determine the adjustment value for an event type, the prediction data analysis computing entity 106 multiplies the field count for the event type by the incidence rate penalty weight for the event type. For example, as depicted in FIG. 12, the prediction data analysis computing entity 106 determines an adjustment value for the diabetes event type by multiplying the field count for the diabetes event type (i.e., 4) by the incidence rate penalty weight for the event type for the diabetes event type (i.e., 3). Moreover, as further depicted in FIG. 12, the prediction data analysis computing entity 106 determines an adjustment value for the kidney-failure event type by multiplying the field count for the kidney-failure event type (i.e., 5) by the incidence rate penalty weight for the event type for the kidney-failure event type (i.e., 2).
The incidence rate penalty weight value is a data object that describes a desired level of magnification in the per-event-type loss value for a corresponding event type before using the per-event-type loss value along with the per-event-type loss values for other event types in order to generate a cross-event-type loss value, where the desired level of magnification is determined in a manner that has an inverse relationship with an overall incidence rate (e.g., an observed overall incidence rate, an assumed overall incidence rate, and/or the like) of the event type among a population of predictive entities. Accordingly, the incidence rate penalty weight values may be determined in a manner configured to penalize deviations between ground-truth event labels and inferred event probability values for less frequent event types relative to more frequent event types. An operational example of generating incidence rate penalty weight values is depicted in FIG. 13. As depicted in FIG. 13, given that the diabetes event type is deemed rarer than the kidney-failure event type, the diabetes event-type is assigned a higher incidence rate penalty weight value relative to the incidence rate penalty weight value of the kidney-failure event-type.
Returning to FIG. 11, at step/operation 1102, the prediction data analysis computing entity 106 determines an adjusted loss value for each event type based at least in part on the per-event-type loss value for the event type and the adjustment value for the event type. In some embodiments, subsequent to determining the adjustment value for an event type, the prediction data analysis computing entity 106 multiplies the adjustment value for the event type by the per-event-type loss value for the event type to determine the adjusted loss value for the event type.
For example, as depicted in FIG. 12, the prediction data analysis computing entity 106 multiplies Loss1, which is the per-event-type loss value for the diabetes event type, by 4*3, which is the adjustment value for the diabetes event type, to generate the adjusted loss value for the diabetes event type. Moreover, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 multiplies Loss2, which is the per-event-type loss value for the kidney-failure event type, by 5*2, which is the adjustment value for the kidney-failure event type, to generate the adjusted loss value for the kidney-failure event type.
At step/operation 1103, the prediction data analysis computing entity 106 determines a combined loss value based at least in part on each adjusted loss value for an event type of the plurality of event types. In some embodiments, subsequent to determining each adjusted loss value for an event type of the plurality of event types based at least in part on the per-event-type type for the event type and the field count of the related subset of the plurality of training data fields associated with the event type, the prediction data analysis computing entity 901 combines (e.g., sums up) the determined adjusted loss values to determine the combined loss value. For example, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 sums up the adjusted loss value for the diabetes event type (i.e. Loss1*4*3) and the adjusted loss value for the kidney-failure event type (i.e., Loss2*5*2) to determine the combined loss value for both the diabetes event type and the kidney-failure event type.
At step/operation 1104, the prediction data analysis computing entity 106 determines a loss normalization factor based at least in part on each adjustment value for an event type of the plurality of event types. In some embodiments, subsequent to determining each adjustment value for an event type of the plurality of event types, the prediction data analysis computing entity 106 determines the loss normalization factor by combining (e.g., summing up) each adjustment value for an event type of the plurality of event types. For example, as depicted in the operational example of FIG. 10, the prediction data analysis computing entity 106 sums up the adjustment value for the diabetes event type (i.e., 4*3) with the adjustment value for the kidney-failure event type (i.e., 5*2) to determine the loss normalization factor.
At step/operation 1105, the prediction data analysis computing entity 106 determines a normalized loss value based at least in part on the combined loss value and the loss normalization factor. In some embodiments, subsequent to determining the combined loss value and the loss normalization factor, the prediction data analysis computing entity 106 determines the normalized loss value based at least in part on the combined loss value and the loss normalization factor. For example, as depicted in FIG. 10, the prediction data analysis computing entity 106 may divide the combined loss value (i.e., Loss1*4*3+Loss2*5*2) by the loss normalization factor (i.e., 4*3+5*2) to determine the normalized loss value.
At step/operation 1106, the prediction data analysis computing entity 106 determines the cross-event-type loss value based at least in part on the normalized loss value. In some embodiments, subsequent to determining the normalized loss value, the prediction data analysis computing entity 106 adopts the normalized loss value as the cross-event-type loss value. In some embodiments, the prediction data analysis computing entity 106 performs one or more adjustment operations (e.g., in accordance with a trained loss aggregation model) to the normalized loss value to generate the cross-event-type loss value.
Returning to FIG. 4, at step/operation 405, the prediction data analysis computing entity 106 trains the multi-event-type prediction model based at least in part on the cross-event type loss value. In some embodiments, the prediction data analysis computing entity 106 updates parameters of the multi-event-type prediction model in order to minimize the cross-event-type loss value. In some embodiments, to update parameters of the multi-event prediction model to minimize the cross-event-type loss value, the multi-event-type prediction model utilizes a training algorithm that uses a local optimization method or a global optimization method, such as gradient descent and/or gradient descent with backpropagation.
At step/operation 406, the prediction data analysis computing entity 106 determines the first-occurrence prediction by processing the prediction input set using the trained multi-event prediction model. The prediction input set may include input properties of a new predictive entity, such as combination of at least one of medical visit data, medical claim data, and demographic data for a patient predictive entity. The first-occurrence prediction is a data object that describes whether the predictive entity is likely to experience first-occurrence of each of two or more event types in a prospective timeframe (e.g., in the next three months). For example, the first-occurrence prediction may describe whether a patient predictive entity is likely to experience diabetes in the next three months and/or likely to experience kidney failure in the next three months. In some embodiments, the first occurrence-prediction comprises a first-occurrence prediction item for each event type of the plurality of event types.
At step/operation 407, the prediction data analysis computing entity 106 performs one or more prediction-based actions based at least in part on the first-occurrence prediction. Examples of prediction-based actions include automated physician notifications, automated patient notifications, automated medical appointment scheduling, automated drug prescription recommendation, automated drug prescription generation, automated implementation of precautionary actions, automated hospital preparation actions, automated insurance workforce management operational management actions, automated insurance server load balancing actions, automated call center preparation actions, automated hospital preparation actions, automated insurance plan pricing actions, automated insurance plan update actions, and/or the like.
In some embodiments, performing the one or more prediction-based actions includes generating a multi-event-type prediction output interface that describes the first-occurrence prediction item for each event type of the plurality of event types, such as the multi-disease prediction user interface 1400 of FIG. 14 that provides a first-occurrence prediction item 1402 for each disease of a group of target diseases 1401. The diseases described by the multi-disease prediction user interface 1400 may be those whose first-occurrence predictions exceed a likelihood threshold. Moreover, the diseases described by the multi-disease prediction user interface 1400 may be ranked according to the magnitudes of deviation of the first-occurrence predictions of the diseases from the likelihood threshold. Accordingly, in some embodiments, more likely diseases may be ranked higher than less likely diseases. In the multi-disease prediction user interface 1400 of FIG. 14, the prediction window may be any number of months, and a prediction window of three months is merely an example of a prediction window.
