Hi! how do i get to the source code of kpca or even better predict.kpca(which it tells me doesn't exist but should) ?
(And if anyone has too much time: Now if i got that right, the @pcv attribute consists of the principal components, and for kpca, these are defined as projections of some random point x, which was transformed into the other feature space -> f(x), projected onto the actual PC (eigenvector of Covariance). This can be computed as the sum of the (eigenvectors of the Kernel matrix * the kernel function(sample_i,x)) Now assume i have some new points and want to project them, how can i do that with only having @pcv? Wouldn't i rather need the eigenvectors of K? ) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
