报告摘要：Recently,there has been a growing interest in applying Newton-type methods tosolve structured

convexoptimization problems that arise in machine learning and statistics.A major obstacle to the design

andanalysis of such methods is that many problems of interest areneither strongly convex nor smooth. In this

talk, wewill present some design techniques for overcoming such obstacle andreport some recent progress

onanalyzing the convergence rates of the resulting Newton-type methodsusing error bounds. We will also

discusssome directions for further study.
