WebJan 9, 2024 · Fisher’s Linear Discriminant, in essence, is a technique for dimensionality reduction, not a discriminant. For binary classification, we can find an optimal threshold t and classify the data accordingly. For … Webare called Fisher’s linear discriminant functions. The first linear discriminant function is the eigenvector associated with the largest eigenvalue. This first discriminant function provides a linear transformation of the original discriminating variables into one dimension that has maximal separation between group means.

WebLinear Discriminant Analysis (LDA) or Fischer Discriminants (Duda et al., 2001) is a common technique used for dimensionality reduction and classification. LDA provides class separability by drawing a decision region between the different classes.
