When I used the java libsvm for regression task. Everything is ok with LINEAR kernel. When I use RBF/POLY/SIGMOID kernel, the output prediction is always the same value. I tried many dataset, the same problem occured every time. But when I tried Python/Matlab libsvm, everything is fine!

I don't see this behaviour when using the Java interface. How are you calling it?

Same problem occurred on me but MATLAB libsvm
