However, we do not hope that a small fraction of object-pairs with very large projection magnitude or margin dominate the complete model.
a piece-wise linear function ψ(•) is applied in S 3 H. As a result, Equation 8is a simply unconstrained optimization problem, which can be efficiently solved by a notable Quasi-Newton algorithm, i.e., L-BFGS (Liu et al., 1989).
