Study compares eight tokenization strategies for ECG transformer models

A new arXiv paper examines how different tokenization choices affect ECG transformer models, since the tokenizer decides both the physiological signal content the model sees and the sequence length attention operates over. The authors benchmark eight tokenization strategies across four architectures — Transformer, Informer, Reformer, and FEDformer — on the nine-label CPSC ECG dataset. The work is cross-listed in cs.AI and cs.LG.

SHIFT-M3 screens multimodal ECG records for cross-patient data mix-ups

A new preprint introduces SHIFT-M3, a method that uses pre-fusion alignment to check whether the waveform, text report, metadata, and predictions bundled in a clinical record actually come from the same patient. The authors note that multimodal clinical AI pipelines usually assume this consistency, yet linkage errors can silently combine individually plausible components from different patients. The approach aims to catch such mismatches before downstream fusion and prediction occur.
