Sparse Autoencoders enhance interpretability in medical imaging foundation models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Sparse Autoencoders (SAEs) to make medical imaging foundation models more interpretable for clinicians. By training SAEs on embeddings from BiomedParse and DINOv3 using a large dataset of CT and MRI slices, the study found that SAEs can reconstruct original embeddings with high fidelity and retain significant downstream performance with drastically reduced dimensionality. The learned sparse features correspond to specific, linguistically expressible concepts, enabling language-driven image retrieval and bridging the gap between clinical language and abstract model representations.

IMPACT This research offers a pathway to more interpretable AI systems in healthcare, potentially increasing clinician trust and adoption of AI tools.

    Sparse Autoencoders for Interpretable Medical Image Representation Learning

    arXiv:2603.23794v2 Announce Type: replace Abstract: Vision foundation models (FMs) achieve state-of-the-art performance in medical imaging. However, they encode information in abstract latent representations that clinicians cannot interrogate or verify. The goal of this study is …
