AI that jointly assesses chronic diseases and depression from wearables

Wearables are reshaping healthcare, but most AI models track one physical condition at a time and overlook depression—despite frequent overlap.

This study reframes multi-disease assessment as a multi-task learning problem, letting one model learn several conditions jointly and use their relationships to improve accuracy.

The catch is “double heterogeneity”: diseases behave differently, and so do patients with the same disease. Enter ADH‑MTL, a method built for both:

• Group-level modeling to generalize to new patients without long personal histories.
• Decomposition to reduce model complexity while preserving key signals.
• Bayesian network to capture dependencies and balance what’s shared vs. unique across tasks.

On real-world wearable data, ADH‑MTL outperformed existing baselines, and each innovation proved effective.

Why it matters: a computational path toward integrated physical and mental healthcare across pre-, during, and post-treatment phases.
