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.
