New diagnostic tool identifies 'dead directions' in LayerNorm transformers
Researchers have identified an algebraic method to detect 'dead directions' in LayerNorm transformers, which are parameter space directions where the Fisher information metric vanishes. This new diagnostic technique, de…

New research explores data manifold geometry with Fisher width and benchmarking
Two new research papers explore the geometry of data manifolds in machine learning. The first paper introduces "Fisher width," a new geometric measure analogous to Gaussian width but adapted for statistical manifolds us…
