In the large field of Principal Component Analysis (PCA), a fairly old technique, there has been lately some advancement that left open a lot of room for improvements. We propose a way to generalize completely the PCA standard and Kernel version (KPCA) from using only the norm in their objective function. Instead a generic one can be used to better fit different datasets and applications and to ultimately outperform the usual norm based PCA. In the literature several attempts with Lp-norms have resulted in pretty good advancement thus using other functions seems to be the logical following. We provide here the mathematical models behind our working algorithms and testing results with different functions on a really large variety of datasets.
