WebAbstract. The Fisher informational metric is unique in some sense (it is the only Markovian monotone distance) in the classical case. A family of Riemannian metrics is called monotone if its members are decreasing under stochastic mappings. These are the metrics to play the role of Fisher metric in the quantum case. WebDec 6, 2024 · In Section 2, we describe our population Fisher Matrix formalism, highlighting the main assumptions and steps to obtain the result. ... The Fisher-matrix prediction can again be obtained from equation , this time with θ = M and λ = α. For sufficiently simple models, the integrals are analytically tractable.
WebWhile the Fisher matrix formalism is limited to yield ellipsoidal confidence contours, our method can reproduce the often observed flexed, deformed or curved shapes of known posteriors. This gain in shape fidelity is obtained by expanding the posterior to higher order in derivatives with respect to parameters such that non-Gaussianity in the ...
