Reaching dual variables in multiclass SVMs

[gumityolcu]

Hello,

I am trying to use Shark to solve multiclass classification problems using the Crammer&Singer method, and I want to reach the dual variables.

How can I manage this?

So far, I have edited the functions so that Solver.solve() returns the RealMatrix alpha variable at the end, instead of the weight vectors. This seems to return a matrix of all 1s.

What would you recommend doing? What do you think I may be misunderstanding?

Thank you.
