Discriminant analysis

WebLinear Discriminant Analysis (LDA) is a well-established machine learning technique and classification method for predicting categories. Its main advantages, compared to other classification algorithms such as neural networks and random forests, are that the model is interpretable and that prediction is easy. WebPartial least squares discriminant analysis (PLS-DA) is a variant used when the Y is categorical. PLS is used to find the fundamental relations between 2 matrices ( X and Y ), i.e. a latent variable approach to modeling the covariance structures in these two spaces.
