WebApr 4, 2024 · Linear discriminant analysis (LDA) is widely studied in statistics, machine learning, and pattern recognition, which can be considered as a generalization of Fisher’s linear discriminant (FLD) (Fisher 1936 ). LDA is designed to find an optimal transformation to extract discriminant features that characterize two or more classes of objects. WebFishers Linear Discriminant To deal with problems with 2 or more classes, most ML algorithms work the same way. Usually, they apply some kind of transformation to the …

From: Biomedical Signal … WebOct 30, 2024 · Step 3: Scale the Data. One of the key assumptions of linear discriminant analysis is that each of the predictor variables have the same variance. An easy way to assure that this assumption is met is to scale each variable such that it has a mean of 0 and a standard deviation of 1. We can quickly do so in R by using the scale () function: # ...
