AI-Based Approaches to Generate Synthetic/Simulated Physiological Signals

Glucose control is an integral component in both preventing and managing diabetes. Without proper control, hyperglycemic and hypoglycemic events can occur, which increase the risks for cardiovascular disease, eye issues, cancer, seizures and more. While continuous glucose monitors are widespread, their lack of computational abilities hinders their utility for behavior change. Additionally, although CGM datasets can be valuable for effective diabetes management, because of annotation effort issues, IRB permissions, under representation of samples, and limited patients, it is difficult to obtain these datasets for creating new and innovative solutions for controlling glucose.
 
Researchers at Arizona State University have developed two novel AI-based approaches, using wearable sensors and machine learning algorithms, to generate synthetic/simulated physiological signals, such as blood glucose.
 
The first approach, GlySynth, uses machine learning algorithms with small amounts of labeled training data to synthesize time-series physiological data from contextual information. This model was trained using a small CGM dataset to map artificial CGM signals belonging to new context – i.e. specific meals, medications and health status. While GlySynth is greatly beneficial in diabetes prevention and management, it could also be used to synthesize other time-series physiological data from contextual information. This means it could be used to generate synthetic time-series data for training a neural network.
 
The second approach, GlySim, is a CGM stimulator that uses multimodal data to not only forecast future glucose readings but also let users examine the impacts of behavior change on glucose response in advance.  It creates opportunities for observing food consumption, medication and physical activity to pinpoint factors that cause anomalous events and how to adjust those behaviors to change glucose trajectories.
