WebFeb 28, 2001 · Principal component analysis (PCA) is a technique which describes the correlation structure, but for only one set of variables. The aim of this paper is to introduce a generalization of PCA to several data tables, generalized principal component analysis (GPCA), which takes into account both correlation structure within sets and relationships ... WebAug 22, 2004 · Principal Component Analysis (PCA) is a well-known dimension reduction scheme. However, since it works with vectorized representations of images, PCA does not take into account the spatial locality of pixels in images. In this paper, a new dimension reduction scheme, called Generalized Principal Component Analysis (GPCA), is …

Existing algebraic subspace clustering methods are based on fitting the data with an algebraic variety and decomposing this variety into its constituent subspaces. Such methods are well suited to the case of a known number of subspaces of known and …
