Removed the '-1' key in the support vector representation. #36

Closed sagi closed 5 years ago

sagi commented 9 years ago

The function get_SV() in svm.py returns the support vectors. It accidently adds a '-1' key in the dictionary that represents a support vector.

The '-1' is used by the C implementation to denote the last svm_node of a vector in the training set x.

Many thanks for pointing out this problem. The patch has been applied for the next release.
