Kernel PCA

Kernel Principal Component Analysis (Kernel PCA) je nelinearna metoda redukcije dimenzionalnosti koju su uveli Bernhard Schölkopf, Alexander Smola i Klaus-Robert Müller 1997–1998. Ona proširuje klasičnu linearnu PCA na zakrivljene, nelinearne podatkovne manofolde implicitnim mapiranjem ulaznih podataka u prostor viših karakteristika putem kernel funkcije, a zatim vrši standardnu PCA u tom prostoru — sve bez eksplicitnog izračunavanja mapiranja.
