Target leakage, not model class, explains reported accuracy in survey-based cardiovascular screening: a leakage-tiered audit of glass-box and tabular foundation models

发生了什么

Researchers audited cardiovascular screening models and found that reported high accuracy comes from data leakage in features, not model sophistication.

为何重要

Healthcare engineers building screening systems should care when evaluating model performance claims from survey-based health datasets.

注意

The study used specific datasets and thresholds; results may not generalize to other screening tasks or populations with different demographic distributions.
