Let P and Q be probability measures over a set X, and let P be absolutely continuous with respect to Q. If μ is any measure on X for which p = d P d μ and q = d Q d μ exist, then the Kullback-Leibler divergence from Q to P is given as. D KL ( P ‖ Q) = ∫ X p log p q d μ.

WebPart 3 - the Fisher information metric on any manifold equipped with a map to the mixed states of some system. Part 4 - the Fisher information metric as the real part of a complex-valued quantity whose imaginary part measures quantum uncertainty. Part 5 - an example: the harmonic oscillator in a heat bath. Part 6 - relative entropy. Part 7 ... WebFeb 16, 2024 · We found that the metric imposes a curvature scalar R on the parameter space. Also, we discovered that R diverges to infinity while approaching bifurcation points. We demonstrate that the local stability conditions are recovered from the interpretations of the curvature R, while global stability is inferred from the character of the Fisher metric.
