Explaining PCA

With this video we are wrapping up with PCA. This last installment will show us that we might gain additional insight into our data if we observe what dimensions comprise a given principal component. We conclude that PCA is generally useful for dimensionality reduction and noise removal.
This video is a part of Introduction to Data Science video series that dives into machine learning, visual analytics, and joys of interactive data analysis using Orange Data Mining software (https://orangedatamining.com).
