WebOct 30, 2012 · So if we can calculate the Fisher Information of a log likelihood function, then we can know more about the accuracy or sensitivity of the estimator with respect to the parameter to be estimated. Figure 2: The variance of the score is called Fisher Information. The Fisher Information denoted by I (θ) is given by the variance of the score. WebFisher Score (Fisher 1936) is a supervised linear feature extraction method. For each feature/variable, it computes Fisher score, a ratio of between-class variance to within-class variance. The algorithm selects variables with largest Fisher scores and returns an indicator projection matrix.
