Arrhythmia Multimodal — research progress viewer

Multi-label ECG classification for life-threatening arrhythmia (classes N / V / S / F / Q) with a dual-path Mamba SSM (Approach A, primary).

Two tracks:

• research/plan.md — the research plan; start here for status and next steps
• research/architecture.md — system design (Approach A primary, B ablation)
• research/approaches.md — A vs B comparison and decision log
• research/data.md — dataset, AAMI mapping, preprocessing protocol
• research/model.md — Mamba SSM design, loss, metrics
• learn/README.md — zero-background lessons, sequential, mapped to plan phases

New docs appear here automatically on every deploy — nothing to configure.
