JEPA pretraining underperforms masked models on MIMIC-IV EHRs
Three joint-embedding formulations trained without collapse but still lost to standard masked language modelling downstream.
Graph-Enhanced Disease Trajectory Discovery and Temporal Endpoint Forecasting from Longitudinal Electronic Health Records
A MIMIC-IV study finds graph branching motifs mainly improve long-range event timing, not endpoint discrimination.
