Mechanisms¶
- Feature Selection
- The notorious trap is selecting and evaluating on the same data, which inflates apparent performance because the subset was fitted to that sample's noise.
This sourceShows that evaluating a rule on samples already used for feature selection produces optimistic, selection-biased error estimates.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
