Towards Fair Medical AI: Adversarial Debiasing of 3D CT Foundation Embeddings

no code implementations5 Feb 2025 Guangyao Zheng, Michael A. Jacobs, Vladimir Braverman, Vishwa S. Parekh

Recently, self-supervised foundation models have been extended to three-dimensional (3D) computed tomography (CT) data, generating compact, information-rich embeddings with 1408 features that achieve state-of-the-art performance on downstream tasks such as intracranial hemorrhage detection and lung cancer risk forecasting.

Demographic Predictability in 3D CT Foundation Embeddings

1 code implementation28 Nov 2024 Guangyao Zheng, Michael A. Jacobs, Vishwa S. Parekh

Our results indicate that the embeddings effectively encoded age and sex information, with a linear regression model achieving a root mean square error (RMSE) of 3. 8 years for age prediction and a softmax regression model attaining an AUC of 0. 998 for sex classification.
