A Tractable Pseudo-Metric on Non-Parametric Exponential Statistical Manifolds via SPD Geometry

Amit Vishwakarma, K. S. Subrahamanian Moosath

The paper proposes a two‑stage method to compute a tractable pseudo‑metric between probability distributions on the non‑parametric Pistone–Sempi exponential manifold by projecting…
