MesomorphicECG XAI

Interactive XAI viewer for Interpretable Mesomorphic Networks (IMN) on PTB-XL ECGs.

  • Models and checkpoints from SEARCH-IHI/mesomorphicECG.
  • Data samples loaded from binary .npz files stored in this Space.
  • Heatmaps show segment-wise IMN contribution per lead.
Sampling rate
Model type

single_linear: single linear head; categorical: 2-class head.

Task (positive class vs NORM)
Record (index | ecg_id | GT | age sex)

Window & stride (segment aggregation)

Top-k leads & segments

Ranked by signed contribution (w·x) to the positive logit: highest positive = most evidence for the selected positive class. Removing them should decrease P(pos_class) for positive-predicting leads.

Ablation (remove top leads/segments and recompute)
