as my title says,I want to get the alpha_i y_i in Libsvm 3.22 but don't know how to do it.
the sv_coef now is a double[][] array and I can't get a_i y_i just use the model.sv_coef[i] like most past answers
I asked the same question in http://stackoverflow.com/q/43348979/3097907 there are some more information there.
I hope anyone can help me with this question ,Thank you.
PS: my original problem is solving this Formula
gradient(J) = -0.5 X sum(a_i X a_j X y_i X y_j X Km(x_i,x_j) )
(from SimpleMKL formula.11 )
