ReTAMamba: Reliability-Aware Temporal Aggregation with Mamba for Irregular Clinical Time Series Prediction

In three linesReTAMamba proposes a Mamba-based architecture for predicting irregular clinical time series. The model estimates observation reliability from missingness and elapsed time, integrates short/long-term information via Chronological Weaving, and uses a budgeted token router. On MIMIC-IV, eICU, and PhysioNet 2012, AUPRC gains of 7.51%, 7.80%, and 10.15% respectively.
