A efficient and accurate solver for MAP inference problems. Compared to state-of-the-art solvers (e.g. TRW-S, AD3, MPLP, etc.), our solvers is orders of magnitude faster without downgrading accuracy.

Fast Structual SVM
A efficient structual SVM solver designed to deal with 1) large factor domain and 2) large number of factors. (for details please check this NIPS 2016 paper)

Efficient solver for multiclass and multilabel classification problems. Designed to solve problems with millions of classes/labels with single core. We're working on a distributed version of this. (for details please check this ICML 2016 paper)
