18.11.2010 · For the example above, I used version 3.0 of LIBSVM (the current stable release at the time this answer was posted).. Finally, w/r/t the part of your question regarding the choice of kernel function, Support Vector Machines are not specific to a particular kernel function--e.g., i could have chosen a different kernel (gaussian, polynomial, etc.).

Modify "def gen_svm_nodearray" in svm.py (LIBSVM) or "def gen_feature_nodearray" in liblinear.py (LIBLINEAR). Here we take "def gen_feature_nodearray"(LIBLINEAR) as an example. The way of modifying "def gen_svm_nodearray"(LIBSVM) is similar. Replace index_range = range(1, len(xi)) else: raise TypeError('xi should be a dictionary, list or tuple')
