Visualizing α-geodesics on the probability simplex: exponential vs mixture geometry
FrnkNlsn · x · 2026-08-25
A visualization note on information geometry: α-geodesics drawn on the probability simplex, comparing the exponential family (red), dual mixture geometry (blue), and Levi-Civita connection (purple). A neat geometric fact: α-pregeodesics coincide when they pass through a simplex vertex. PDF linked.
