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. Specifically, one has See more A slightly more formal, abstract definition can be given, as follows. Let X be an orientable manifold, and let $${\displaystyle (X,\Sigma ,\mu )}$$ be a measure on X. Equivalently, let $${\displaystyle (\Omega ,{\mathcal {F}},P)}$$ See more Given a statistical manifold with coordinates $${\displaystyle \theta =(\theta _{1},\theta _{2},\ldots ,\theta _{n})}$$, one writes $${\displaystyle p(x,\theta )}$$ for the probability distribution as a function of $${\displaystyle \theta }$$. Here $${\displaystyle x}$$ is … See more The action of a curve on a Riemannian manifold is given by The path parameter … See more The above manipulations deriving the Fisher metric from the Euclidean metric can be extended to complex projective Hilbert spaces. In this case, one obtains the Fubini–Study metric. This should perhaps be no surprise, as the Fubini–Study … See more

WebMay 22, 1995 · A statistical parameter estimation theory for quantum pure state models is presented. We first investigate the basic framework of pure state estimation theory and derive quantum counterparts of the Fisher metric.

WebFisher information [19]). While the relation between Fisher metric and Markovianity has been previously partially ana-lyzed [20] here we characterize it completely. In fact, a key characterisation of the Fisher metric is given by the Chentsov’s theorem: this says that the Fisher information is the unique Riemannian WebIdeal for measuring the outside diameter of stoppers, the inside diameter of tubing, and the depth of vials.
