New method measures singular structure in neural networks

Researchers have developed a new method to measure and classify the singular structure within trained neural networks without relying on descent or alignment. This technique, detailed in a new arXiv paper, allows for the recovery of the order of dead directions and distinguishes genuine singularities from gauge symmetries. The approach has been demonstrated on various layer types, including transformers and MLPs, and successfully recovers architecture-predicted orders in both constructed and trained networks. AI

    Measuring Dead Directions: Decomposing and Classifying Singular Structure off Canonical Alignment

    We give a descent-free, alignment-free measurement of singular structure on trained networks. At a single frozen checkpoint the read recovers the order $k$ of each dead direction from the directional-Fisher rate, the master invariant from which the per-direction learning coeffici…
