GeoSAE framework uses geometry to interpret brain MRI foundation models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed GeoSAE, a novel framework designed to interpret the clinical information encoded within brain MRI foundation models. This method addresses the challenge of feature collapse in deep transformer layers and the confounding effects of aging in Alzheimer's disease research. By utilizing the model's learned manifold structure, GeoSAE identifies a compact and interpretable set of features that can predict the conversion from mild cognitive impairment to Alzheimer's disease with significant accuracy.

    GeoSAE: Geometric Prior-Guided Layer-Wise Sparse Autoencoder Annotation of Brain MRI Foundation Models

    arXiv:2605.01829v1 Announce Type: new Abstract: Brain MRI foundation models learn rich representations of anatomy, but interpreting what clinical information they encode remains an open problem. Standard sparse autoencoders (SAEs) suffer from severe feature collapse in deep trans…
