PCA is a dimensionality reduction framework in machine learning. According to Wikipedia, PCA (or Principal Component Analysis) is a “statistical procedure that uses orthogonal transformation to convert a set of observations of possibly correlated variables…into a set of values of linearly uncorrelated ...
