Learning Objectives
By the end of this chapter, you will be able to:
Implement feature engineering techniques such as discretization, one-hot encoding, and transformation
Execute feature selection methods on a real-world dataset using univariate feature selection, correlation matrix, and model-based feature importance ranking
Apply feature reduction using principal component analysis (PCA) for dimensionality reduction, variable reduction with clustering, and linear discriminant analysis (LDA)
Implement PCA and LDA and observe the differences between them
