WebMar 21, 2024 · Just like the Shannon entropy leads to derived useful concepts like the KL distance between distributions, the Fisher information also has derived concepts that can be similarly useful. E.g., the relative Fisher information is the analog to the KL distance between two distributions, and is given by . for any two distributions . and . There is ... WebIn 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 parameter θ of a distribution that models X.Formally, it is the variance of the score, or the expected value of the observed information..
