, i ij j l = for each pair of xi and . x j The resulting N N # matrix K with entries k , ij is called the kernel matrix. 3) Train the given linear pattern analysis method A using the kernel matrix and the training data set, and obtain a pattern function () (, ), fk xx x ii i N 1 a = = / where i a (, ,) iN 1 g = are obtained by training.
