The Fisher's Linear Discriminant

摘要

In this paper we have chosen a proper vector b in order to prove that the MSE discriminant function a~lY is directly related to Fisher's linear discriminant. The Fisher's criterion is in the range of techniques for performing linear discrimination in the two class case. The Fisher's linear discriminant is a criterion function that involves all of the samples, while the perceptron criterion function is focussed on the misclassified samples.
