Machine Learning and Data
Given two data sets (MaleData, FemaleData) in which each row is a sample with 18 features, please perform the following operations:
1. Merge these two data sets and find/plot the covariance matrix for the merged data set.
2. Apply PCA and LDA transformations to the merged data set, respectively. Also, find/plot the covariance
matrices for transformations, respectively. Describe the phenomena that you have observed.
3. Use the first two principal components of PCA as well as the first two eigenvectors of LDA to represent the merged data set. Selectively plot portions of samples from MaleData and FemaleData, respectively. Describe the phenomena that you have observed.
