WebDec 22, 2024 · To understand Linear Discriminant Analysis we need to first understand Fisher’s Linear Discriminant. Fisher’s linear discriminant can be used as a supervised learning classifier. Given labeled data, the classifier can find a set of weights to draw a decision boundary, classifying the data.
