AI uncertainty quantification flawed in imbalanced clinical data, study finds

A new research paper published on arXiv highlights a critical flaw in uncertainty quantification for selective prediction systems used in clinical settings, particularly when dealing with imbalanced datasets. The study demonstrates that standard uncertainty measures can misrepresent clinical ambiguity, instead acting as a proxy for class membership and systematically penalizing minority patient groups. Researchers propose a corrected framework that aligns uncertainty measures with clinical thresholds, ensuring balanced risk across different patient groups and improving the safety of AI in healthcare.

    When uncertainty quantification fails: structural vulnerabilities and corrections for selective prediction under clinical class imbalance

    arXiv:2610.37561v1 Announce Type: cross Abstract: Background. Selective prediction systems improve the safety of clinical artificial intelligence by deferring ambiguous cases to human experts while automating high-confidence decisions. However, this safety mechanism relies entire…
