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 ... WebOct 1, 2024 · Fisher scores have been utilized to extract fixed-length representation vectors from the MIL bags with the assistance of generative models. However, the generative model utilized by the existing methods might disregard the covariance information.
