Medical AI models exhibit "memorisation bias" impacting patient diagnoses

A new research paper published on arXiv details a phenomenon termed "memorisation bias" in medical AI models. This bias occurs when a model, trained on a patient's historical data, is later used to assess that same patient's future data. The study demonstrates that this can lead to significantly altered predictions, with diagnostic sensitivity decreasing for new conditions and sensitivity and specificity inflating for unchanged health states. The findings highlight a previously unrecognized risk in medical AI deployment, suggesting a need to revise current training and deployment protocols to account for patients who have contributed to the training data.

IMPACT Highlights a previously uncharacterized risk in medical AI deployment, potentially requiring changes to training and deployment protocols.

    Memorisation bias in medical AI

    arXiv:2609.17223v1 Announce Type: new Abstract: Medical AI models hold immense potential to improve patient outcomes, but they are also known to unintentionally memorise individual records from their training datasets. While such memorisation has been linked to targeted privacy a…
