For a discrete probability space, that is, a probability space on a finite set of objects, the Fisher metric can be understood to simply be the Euclidean metric restricted to a positive "quadrant" of a unit sphere, after appropriate changes of variable. Consider a flat, Euclidean space, of dimension N+1, parametrized … See more In information geometry, the Fisher information metric is a particular Riemannian metric which can be defined on a smooth statistical manifold, i.e., a smooth manifold whose points are probability measures defined … See more The Ruppeiner metric and Weinhold metric are the Fisher information metric calculated for Gibbs distributions as the ones found in equilibrium statistical mechanics. See more The Fisher metric also allows the action and the curve length to be related to the Jensen–Shannon divergence.
