In Proceedings of the 3rd International Workshop on Knowledge Discovery in Healthcare Data co-located with the 27th International Joint Conference on Artificial Intelligence and the 23rd European Conference on Artificial Intelligence (IJCAI-ECAI), 64–68, Jul 2018.

Low-cost sensors continuously measuring blood glucose levels in intervals of a few minutes and mobile platforms combined with machine- learning (ML) solutions enable personalized pre- cision health and disease management. ML solu- tions must be adapted to different sensor technolo- gies, analysis tasks and individuals. This raises the issue of scale for creating such adapted ML solu- tions. We present an approach for predicting blood glucose levels for diabetics up to one hour into the future. The approach is based on recurrent neural networks trained in an end-to-end fashion, requir- ing nothing but the glucose level history for the pa- tient. The model outputs the prediction along with an estimate of its certainty, helping users to inter- pret the predicted levels. The approach needs no feature engineering or data pre-processing, and is computationally inexpensive.
