WebThe relationship is actually based on the code he translated from the C++ implementation: decision = decision_function (params, sv, nv, a, b, X); votes = [ (i if decision [p] > 0 else j) for p, (i,j) in enumerate ( (i,j) for i in range (len (cs)) for j in range (i+1,len (cs)))]. The highest vote out of votes is basically what predict does.
