Every data scientist, especially the ones that find themselves to work with Big Data, knows the importance of dimensionality reduction. If you have a dataset that has a large amount of columns and you have a Machine Learning task to complete:
So it is important to know and understand some dimensionality reduction techniques and one of the most famous one is the Principal Component Analysis** (P.C.A.).**
