Practical Inexact Proximal Quasi-Newton Method with Global Complexity Analysis
Katya Scheinberg, Xiaocheng Tang
Recently several methods were proposed for sparse optimization which make careful use of second-order information [10, 28, 16, 3] to improve local convergence rates. These methods…

Efficiently Using Second Order Information in Large l1 Regularization Problems
Xiaocheng Tang, Katya Scheinberg
We propose a novel general algorithm LHAC that efficiently uses second-order information to train a class of large-scale l1-regularized problems. Our method executes cheap iteratio…
