Yanbo Liang commented on SPARK-10078: ------------------------------------- [~sethah] The description is a little misleading, it means the VL-BFGS implementation can fit the current API. Feature partitioning (VL-BFGS) or not (Breeze LBFGS) will be choose automatically depends on the number of features. The purpose of VL-BFGS is not to replace Breeze LBFGS, but as a complementary method.
