A New Method Combining LDA and PLS for Dimension Reduction
Figure 5
Relationship between the number of PLS latent variables, PLS-LDA, LDA-PLS and ex-LDA-PLS algorithm performance.
Red lines with up triangle represent the results of ex-LDA-PLS, blue lines with left triangle are LDA-PLS classification results, green lines with circle are the PLS-LDA results, cyan lines with star are the PLS results. Square and star represent the training set and testing set, respectively.
