Structural SVM Multiclass Implementation on Matlab

SSVM Classify Multiclass SVM  Implementation  on MATLAB by solving Quadratic Programming on Primal (CVX) and Dual (Matlab quadproc)
According to Crammer and Singer forumation.

[1] K. Crammer and Y. Singer. On the Algorithmic Implementation of Multi-class SVMs, JMLR, 2001.

This code is Matlab implementation of the following Multiclass Structural SVM
http://www.cs.cornell.edu/people/tj/svm_light/svm_multiclass.html


        min 1/2 Σ_i=1..k w_i*w_i + C/n Σ_{i = 1..n} ξ_i
         s.t. for all y in [1..k]: [ x₁ • w_yi ] >= [ x₁ • w_y ] + 100*Δ(y₁,y) - ξ_{1
                    ...}
                   for all y in [1..k]: [ x_n • w_yn ] >= [ x_n • w_y ] + 100*Δ(y_n,y) - ξ_n


Usage: Call run_myownSSVM_myQuadprocMulticlassSVM on Matlab


Change the variable dual_qp to true for solving on Dual objective function
Change the variable dual_qp to false for solving on Primal objective function
