Gumbel-Copula Selector Improves Clinical Tail Feature Selection
|
7.1
Researchers propose a supervised feature-selection filter using a Gumbel-copula implied upper-tail concordance score (lambda U) in a paper updated on Feb 24, 2026. They evaluate lambda U on a CDC public-health survey (N=253,680) and the PIMA clinical benchmark (N=768), showing faster selection and reduction from 21 to 10 CDC features with small but significant trade-offs, and comparable or improved ranking versus common baselines.
Scoring Rationale
Validated, efficient tail-aware feature selector across large clinical datasets, limited by arXiv preprint status and incremental novelty.
