Learning disentangled representations for explainable chest X-ray classification using Dirichlet VAEs

no code implementations6 Feb 2023 Rachael Harkness, Alejandro F Frangi, Kieran Zucker, Nishant Ravikumar

We generate visual examples to show that our explainability method, when applied to the trained DirVAE, is able to highlight regions in CXR images that are clinically relevant to the class(es) of interest and additionally, can identify cases where classification relies on spurious feature correlations.
