WebNov 11, 2024 · LDA is the conventional discriminant analysis technique which takes squared L2-norm as the distance metric. The others use L1- or L2,1-norm distance metrics. The projection for each of the methods is learned on the training set, and used to evaluate on the testing set. Finally, nearest neighbour classifier is employed for image …
