Model implementation
Adds EHRMamba, a Mamba model for electronic health records.
Closely modeled off of the paper - EHRMAMBA: Towards Generalizable and Scalable Foundation Models for Electronic Health Records
Main work:
pyhealth/models/ehrmamba.py: New module with
RMSNorm,MambaBlock(SSM with causal conv), andEHRMamba(BaseModel). Uses existingEmbeddingModel, per-feature Mamba stacks, andget_last_visitfor the classification head. Compatible with current PyHealth tasks and Trainer.Testing and example notebook will also be included. I also included an icustays csv file because the mimic4ehrdataset class has default table icustays which is not present anywhere in the codebase.
