ECG classification: evaluation before architecture

Abstract

Patient leakage, imbalance, uncertainty, and other decisions that matter before selecting a model.

Problem framing

The useful question is not which technique sounds most advanced, but which assumptions fit the data-generating process and the cost of failure. Specify the unit of generalization, prevent leakage, and decide what evidence would change the conclusion.

Method lens

Model choice is an inductive-bias decision. Simple baselines, carefully designed representations, and repeated evaluation often reveal more than an architecture comparison alone.

Evaluation before conclusion

  • Split at the level of the intended generalization claim.
  • Report variation across repetitions or folds when available.
  • Compare relevant baselines under the same protocol.
  • Separate retrospective discrimination from operational utility.
  • Record preprocessing, configuration, and expected outputs.

Limitations

This is a research-communication note, not clinical, diagnostic, or investment guidance. It condenses method choices and does not replace the underlying paper, dataset documentation, or domain-expert review.
