At layer 9, GeoSAE found many more alive features than a standard SAE and reduced feature redundancy. GeoSAE's top layer-9 features were all clinically annotated rather than non-specific. GeoSAE is a three-stage pipeline for interpreting frozen brain MRI foundation model embeddings. GeoSAE was designed to handle feature mortality, age confounding, and comorbidity confounding in brain MRI foundation models.
