WebKernel Canonical Correlation Analysis (KCCA) is a non-linear extension of CCA. Given two random variables, KCCA aims at extracting the information which is shared by the two random variables. More precisely given x x and y y the purpose of KCCA is to provide nonlinear mappings f (x) f (x) and g (y) g(y) such that their correlation is maximized.
