Improving Multi-Sensor Non-Invasive Glucose Detection through AI:A Domain Generalization Approach
Bibliographic record
Abstract
Accurate glucose level monitoring is crucial in diabetes management, aiming to ensure glucose levels are within a safe range and reduce the risk of complications. Inter-patient heterogeneity is one of the most important challenges to achieving accurate non-invasive glucose monitoring. This study employs meta-forests, a novel ensemble-based domain generalization approach designed to address this challenge. Our technique is applied to a dataset of 54,280 data points, collected from five subjects over 10 days, using a non-invasive system that integrates near-infrared (NIR) spectroscopy, millimeterwave (mm-wave) sensing, and temperature measurements. Moreover, we significantly enhance model interpretability by incorporating Shapley additive explanations (SHAP) analyses. Importantly, our approach leads to an accuracy for the non-invasive glucose detection system that is comparable to state-of-the-art methods, achieving an average root mean square error (RMSE) of 1.07 mmol/L and a mean absolute percentage error (MAPE) of 9.80% in domainspecific<br/>experiments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
