The 3rd International Workshop on Knowledge Discovery in Healthcare Data


Blood Glucose Level Prediction Challenge

Blood glucose level (BGL) prediction is a challenging task for AI researchers, with the potential to improve the health and wellbeing of people with diabetes. Knowing in advance when blood glucose is approaching unsafe levels provides time to pro-actively avoid hypo- and hyperglycemia and their concomitant complications. The drive to perfect an artificial pancreas has increased the interest in using machine learning (ML) approaches to improve prediction accuracy. Work in this area has been hindered, however, by a lack of real patient data; some researchers are only able to work on simulated patient data.

In the Machine Learning Blood Glucose Level Prediction (BGLP) Challenge, researchers will come together to compare the efficacy of different ML prediction approaches on a standard set of real patient data, the OhioT1DM Dataset. Training data is available now. Test data will be released shortly before the Challenge. Participants will use the same data with their own diverse prediction approaches, and we will come together as a group to compare results and share experiences. We believe that this will foster continuing collaboration and accelerate the pace of progress in the field.

The OhioT1DM Dataset

The OhioT1DM Dataset contains 8 weeks worth of data for each of 6 people with type 1 diabetes. These people were all on insulin pump therapy with continuous glucose monitoring (CGM). They reported life-event data and provided physiological data from a Basis Peak fitness band. The dataset includes: a CGM blood glucose level every 5 minutes; blood glucose levels from periodic self-monitoring of blood glucose (finger sticks); insulin doses, both bolus and basal; self-reported meal times with carbohydrate estimates; self-reported times of sleep, work, and exercise; and 5-minute aggregations of heart rate, galvanic skin response (GSR), skin temperature, air temperature, and step count.

To protect the data and ensure that it is used only for research purposes, a Data Use Agreement (DUA) is required. Researchers can click here to Request the Data Use Agreement for the OhioT1DM Dataset. An initial draft of the dataset description paper is available here: The OhioT1DM Dataset for Blood Glucose Level Prediction.

Participate in the Challenge!

To facilitate "apples to apples" comparisons, participants are asked to report results for a 30-minute prediction horizon, as specified in How to Report Results.

Submission requirements are detailed in the Call for Papers. Deadlines are posted with the Important Dates.
