Abstract 

We establish an excess risk bound of 图片.png for ERM with an H-smooth loss function and a hypothesis class with Rademacher complexity 图片.png , where 图片.png is the best risk achievable by the hypothesis class. For typical hypothesis classes where 图片.png图片.png this translates  to  a learning rate of 图片.png in the separable 图片.pngcase and 图片.png generally. We also provide similar guarantees for online and stochastic convex optimization of a smooth non-negative objective.
