search for: trainingdatay

...I am using a custom kernel, so i use the kernel="matrix" option of the ksvm method. My (normalized) kernel matrix is of size 1309*1309, my results vector has the same length. I am using C-svc. My kernlab call is something similiar to this: ksvm(kernel="matrix", kernelMatrix, trainingDataYs, type="C-svc", cross=10, C=2) To this point, everything works fine. But now, i want to do a search for a good C Parameter, so I call the ksvm method multiple times in a loop, with changing parameters. This loop freezes after a few iterations. The following simple example also freezes...
