Abstract: Systems, devices, and methods for data collection and development as well as providing user interaction policies are provided. In one embodiment, a method includes collecting contextual data for a first subset of a plurality of users. The method further includes generating a first set of contextual profiles for the first subset of the plurality of users based on the collected contextual data. Additionally, the method includes training one or more imputation models to develop the contextual data for the second subset of the plurality of users. The method also includes generating the contextual data for the second subset of the plurality of users using the one or more imputation models. Further, the method includes generating a second set of contextual profiles for the second subset of the plurality of users based on the generated contextual data for the second subset of the plurality of users.

Abstract: A method for predicting disease is provided. The method includes generating biased analyte data by adding analyte sensor bias to historical analyte data, associating the biased analyte data with clinical disease diagnoses associated with the historical analyte data, and extracting features from the biased analyte data. The method further includes, for each model of a number of models, generating disease predictions based on different combinations of the features extracted from the biased analyte data, and evaluating the disease predictions based on the clinical disease diagnoses associated with the biased analyte data. The method further includes selecting a model and a combination of features based on a performance metric and a robustness metric.

Abstract: Certain aspects of the present disclosure relate to methods and systems for predicting glycemic events in a patient induced as a result of physical activity. In certain aspects, a method includes monitoring a plurality of analytes of the patient continuously during a time period to obtain analyte data, the plurality of analytes including at least glucose and lactate. The method further includes processing the analyte data from the time period to determine an intensity level of physical activity engaged by the patient during the time period. The method further includes generating a glycemic event prediction using at least the analyte data for the plurality of analytes and the determination of physical activity intensity. The method further includes generating one or more recommendations for treatment for the patient based, at least in part, on the glycemic event prediction.
