Dear all,
I am new to scikit learn and I want to ask a question about the SVM module.
Does the SVM module support non-psd kernel matrix?
Ive found that in the web page ("
http://scikit-learn.org/stable/modules/svm.html";) there are lines about the
kernel matrix:
>1.2.7.1. SVC
>....
> Q is an n by n positive semidefinite matrix, Q_{ij} \equiv K(x_i, x_j)
and \phi (x_i)^T \phi (x) is the kernel.
Does this imply that the SVC module only support psd kernel matrix?
Thank you.
Best Regards,
Benjamin Li
