WebThe Fisher Score is an effective criterion for judging the sample features, derived from Fisher’s linear discriminant, which finds feature subsets in the feature set space that maximize the distance between different categories of data points while minimizing the distance between those in the same category. WebIn the course I'm following, this is how Fisher Information is defined. Makes life simpler indeed :) – alisa Jan 23, 2024 at 6:30 Yes, I give my students both formulas so they can choose. In cases in which the derivatives get too complicated, the first one might be a better choice, but in most usual examples that is not the case.
