TreeText-CTS: Compact, Source-Traceable Tree-Path Evidence for Irregular Clinical Time-Series Prediction

In three linesTreeText-CTS converts irregular EHR trajectories into human-readable, source-traceable evidence units derived from XGBoost tree paths. The system improves AUPRC by 6.0–9.7 absolute percentage points on PhysioNet 2012, MIMIC-III, and PhysioNet 2019 while remaining competitive with numerical time-series models.
