@geffy frist thank you for provide us this good tool,but in fact sometime there some question of multi-class .Could you give some advises.

Hi @Darinyazanr! I know how to implement (I mean efficiently) multi-class for 2nd order, but it is not so easy for an arbitrary order. If you don't care about computational efficiency, it's possible to use one of multiclass-to-binary reduction technique (e.g. One-Vs-All approach)
