Principal Component Analysis in Python

Pca regression python example gutenberg castle liechtenstein castles Principal Components Regression, Pt. The need for pruning. The purpose of this article is to set the stage for presenting dimensionality reduction techniques appropriate for predictive modeling, such as y-aware principal components analysis, variable pruning, L2-regularized regression, supervised PCR, or partial least squares.

Let's quickly find out the amount of information or variance the principal components hold. Remember that there is some semantic class overlap in this dataset which means that a frog can have a slightly similar shape of a cat or a deer with a dog; especially when projected in a two-dimensional space. The differences between them might not be captured that well. The points belonging to the same class are close to each other, and the points or images that are very different semantically are further away from each other.
