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/kerncomp1-e.htmlAlso, it is a kernel matrix for high-dim 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?)
