Member Function Documentation

void addconstraint ( const ::std::vector< float64_t > &  normw2, const float64_t  sumofpositivealphas  )

virtual

adds a constraint to the LP arising in L1 MKL based on two parameters

Parameters

normw2	is the vector of for all kernels
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.

Reimplemented from MKLMultiClassOptimizationBase.
