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's idea was that if we wanted to find one direction, good classification should be obtained based on the projected data. His idea was to maximize the ratio of the between-class variance and the within- class variance. Roughly speaking, the “spread” of the centroids of every class is maximized relative to the “spread” of the data ...
