adds a constraint to the LP arising in L1 MKL based on two parameters
normw2 | is the vector of ![]() |
sumofpositivealphas | is a term depending on alphas, labels and biases, see in the function float64_t getsumofsignfreealphas() from MKLMultiClass.h, it depends on the formulation of the underlying GMNPSVM. |
