Will you please mention what a kernel matrix is? Thank you! =) .... okay so (correct me where i'm wrong) but i think it is a type of similarity matrix, ref: http://www.cbrc.jp/~kato/kerncomp1/kerncomp1e.htmlAlso, it is a kernel matrix for highdim data that lies on/near a low dim manifold which: 1. implicitly maps data into a nonlinear feature space 2. is constructed by maximizing var of feature space, subject to local constraints to preserve angles and distances between nearest neighbors. (.. so is it a conformal mapping in neighborhoods?) ref http://delivery.acm.org/10.1145/1020000/10...35&CFTOKEN=64122404Edited 11162006 04:37 PM
