WebJan 9, 2024 · Some key takeaways from this piece. 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 multiclass data, we can (1) model a class conditional distribution using a Gaussian. WebJun 14, 2016 · Fisher Linear Dicriminant Analysis. The implemented function supports two variations of the Fisher criterion, one based on generalised eigenvalues (ratio trace criterion) and another based on an iterative solution of a standard eigenvalue problem (trace ratio criterion). The later implementation, is based on.
