New research explores data manifold geometry with Fisher width and benchmarking

By PulseAugur Editorial · [5 sources] ·

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 using the Fisher information metric. This measure captures anisotropic geometric effects and is applied to prove generalization bounds for Fisher-Lipschitz hypothesis classes. The second paper presents a benchmarking framework for studying data geometry, using repurposed datasets and specialized estimators to analyze properties like curvature and reach, aiming to bridge the gap between deep learning theory and practice.
