Web6.2. Formulas for PCA. From a matrix standpoint, PCA consists of studying a data matrix Z Z, endowed with a metric matrix Ip I p defined in Rp R p, and another metric N N defined in Rn R n (generally N = (1/n)In N = ( 1 / n) I n ). under a normalized PCA: Z =XS−1 Z = X S − 1, where S S is the diagonal matrix of standard deviations. WebPrincipal Component Analysis (PCA) is a linear dimensionality reduction technique that can be utilized for extracting information from a high-dimensional space by projecting it into a lower-dimensional sub-space. It tries to preserve the essential parts that have more variation of the data and remove the non-essential parts with fewer variation ...
