Most of the variation, which is easy to visualize and summarise the feature of original high-dimensional datasets in The first component has the largest variance followed by the second component and so on.New set of uncorrelated variables called principal component (PC) while retaining the most possible variation. PCA reduces the high-dimensional interrelated data to low-dimension by linearly transforming the old variable into a.Method that used to interpret the variation in high-dimensional interrelated dataset (dataset with a large number of variables) PCA is a classical multivariate (unsupervised machine learning) non-parametric dimensionality reduction.What is Principal component analysis (PCA)?
