This research introduces a novel deep learning architecture for personalized blood glucose forecasting in Type 1 Diabetes by explicitly modeling inter-subject variability through subject conditioning. The approach addresses critical limitations in existing population-level models, offering improved early detection of adverse glycemic events via advanced temporal dynamics and multimodal data integration. While the application is medical, the core innovation lies entirely within machine learning methodologies for time-series prediction and personalization.
Subject-Conditioned Glucose Forecasting in Type-1 Diabetes
arXiv:2607.19006v1 Announce Type: new Abstract: Accurate forecasting of blood glucose concentration is key in the management of Type 1 Diabetes, facilitating early detection of adverse glycemic events and supporting timely therapeutic interventions. Despite recent advances in glucose prediction, most existing approaches rely on population-level representations or implicit personalization strategies that fail to deliver effective subject-specific forecasts. In this work, we propose Subject-Conditioned Glucose Prediction (SCGP), a novel multimodal deep learning architecture conceived for personalized blood glucose prediction. SCGP conditions glucose predictions based on observed glucose data and a compact subject-specific representation learned from contextual information. By explicitly separating subject characterization from glucose dynamics modeling and avoiding early fusion of heterogeneous inputs, the proposed framework effectively captures inter-subject variability while preserving robust and reliable temporal modeling. Experiments on two state-of-the-art benchmark datasets demonstrate that SCGP consistently improves forecasting performance, enabling reliable detection of adverse glycemic events across multiple prediction horizons, highlighting the benefits of explicit subject conditioning for personalized diabetes management.
