AI models scale improves linear recoverability, not native geometry

A new research paper explores the Platonic Representation Hypothesis (PRH), which suggests larger AI models learn similar representations of the world. The study, using embeddings from the Legacy Survey and Hyper Suprime-Cam, found that alignment techniques improve the linear recoverability of these representations across datasets. However, this improvement did not translate to a convergence in the native cosine geometry of the embeddings, indicating that while models can be aligned to share information linearly, they do not necessarily converge to a shared underlying metric geometry as they scale. AI

IMPACT Suggests that while larger models can be aligned to share information linearly, they may not converge to a shared underlying metric geometry.
