The Fisher information is used in machine learning techniques such as elastic weight consolidation, which reduces catastrophic forgetting in artificial neural networks. Fisher information can be used as an alternative to the Hessian of the loss function in second-order gradient descent network training. Relation to … Prikaži več In mathematical statistics, the Fisher information (sometimes simply called information ) is a way of measuring the amount of information that an observable random variable X carries about an unknown … Prikaži več Chain rule Similar to the entropy or mutual information, the Fisher information also possesses a chain rule … Prikaži več Optimal design of experiments Fisher information is widely used in optimal experimental design. Because of the reciprocity of estimator-variance and Fisher information, minimizing the variance corresponds to maximizing the information. Prikaži več The Fisher information was discussed by several early statisticians, notably F. Y. Edgeworth. For example, Savage says: "In it [Fisher information], he [Fisher] was to some extent anticipated (Edgeworth 1908–9 esp. 502, 507–8, 662, 677–8, 82–5 and … Prikaži več The Fisher information is a way of measuring the amount of information that an observable random variable $${\displaystyle X}$$ carries about an unknown Prikaži več When there are N parameters, so that θ is an N × 1 vector $${\displaystyle \theta ={\begin{bmatrix}\theta _{1}&\theta _{2}&\dots &\theta _{N}\end{bmatrix}}^{\textsf {T}},}$$ then the Fisher information takes the form of an N × N Prikaži več Fisher information is related to relative entropy.
