This package contains 5 MATLAB codes implementing a comprehensive face recognition pipeline: 1) saveORLimage.m divides ORL face database into test set (ptest) and training set (pstudy), saved as imagedata.mat; 2) savelda.m performs PCA dimensionality reduction followed by LDA feature extraction, generating new test set (ldatest) and training set (ldastudy) saved as imageldadata.mat; 3) discretimage.m discretizes ldastudy data into discrete matrix disdata, stored as imagedisdata.mat; 4) savers.m constructs decision tables from disdata

A machine learning course assignment implementing PCA (Principal Component Analysis) and LDA (Linear Discriminant Analysis) for dimensionality reduction. Unlike many online resources with sparse comments, this implementation includes comprehensive annotations and attention to implementation details. Features a comparative Naive Bayes classifier and uses the OLR face image dataset. Important: ReducedDim parameter specifies the exact number of features to extract, not a percentage.
