Dimensionality Reduction

Modules

 Principal Component Analysis
 Produces a model that transforms a number of (possibly) correlated variables into a (smaller) number of uncorrelated variables called principal components.
 
 Principal Component Projection
 Projects a higher dimensional data point to a lower dimensional subspace spanned by principal components learned through the PCA training procedure.
 

Detailed Description

A collection of methods for dimensionality reduction.
