Two estimates I^ of the Fisher information I X( ) are I^ 1 = I X( ^); I^ 2 = @2 @ 2 logf(X j )j =^ where ^ is the MLE of based on the data X. I^ 1 is the obvious plug-in estimator. It can be di cult to compute I X( ) does not have a known closed form. The estimator I^ 2 is

Web4. By definition, the Fisher information is equal to the expectation. where is a parameter to estimate and. denoting by the probability distribution of the given random variable . The expectation value is taken w.r.t . In other words. for a continuous random variable and similarly for discrete ones. Just use that. WebENC = VL_FISHER (X, MEANS, COVARIANCES, PRIORS) computes the Fisher vector encoding of the vectors X relative to the Gaussian mixture model with means MEANS, covariances COVARIANCES, and prior mode probabilities PRIORS.
