Weyl symmetry of the gradient-flow in information geometry
Tatsuaki Wada, Sousuke Noda · arXiv (Cornell University) · 2025
We have revisited the gradient-flow in information geometry from the perspective of Weyl symmetry. The gradient-flow equations are derived from the proposed action which is invariant under the Weyl's gauge transformations. In Weyl integrable geometry, we have related Amari's $α$-connections in IG to the Weyl invariant connection on the Riemannian manifold equipped with the scaled metric.
