Researchers have introduced "geometric stability" as a new metric to evaluate neural network representations, complementing existing methods like CKA and Procrustes distance. This new metric, called Shesha, quantifies how reliably a representation's structure can be recovered, addressing a gap in current analysis that only measures similarity. Experiments across thousands of encoder configurations and numerous vision models, including DINOv2, reveal that geometric stability can be dissociated from representational similarity, indicating it captures a distinct and important property of learned representations.
