Abstract
A research note on similarity geometry, patient-wise evaluation, and what the QADK study does—and does not—show.
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.
