Using a kernel, the originally linear operations of PCA are performed in a reproducing kernel Hilbert space. WebDec 20, 2024 · Introduction. The central idea of principal component analysis (PCA) is to reduce the dimensionality of a data set consisting of a large number of interrelated variables while retaining as much as possible of the variation present in the data set. This is achieved by transforming to a new set of variables, the principal components (PCs), which ...
