jecos integrated as the default qpsolve in ALS; implicit tests are failing
Qp options added to Spark ALS: unbounded Qp, Qp with pos, Qp with bounds, Qp with smoothness, Qp with L1
Prepared branch of ALS-QP feature/runtime testing
QpProblem drivers in MovieLensALS
debug option for octave quadprog validation
L1 option added to ALS; Driver added to MovieLensALS
Qp with equality and bounds added to option 4 of ECOS based QpSolver
Movielens runtime experiments for Spark Summit talk
ADMM based QuadraticMinimizer in mllib.optimization;Used in ALS
Refactored to use com.github.ecos package
moved interior point based qp-als to feature/ipmqp-als branch; preparing for distributed runs; rho=50 for equality constraint, default rho=1.0, alpha = 1.0 (no over-relaxation) for convergence study
