Webshowing that second-order methods are faster than rst-order methods in many practical problems [7,11,20,33]. In particular, Mokhtari et al. propose a stochastic BFGS algorithm with a O(1=k) convergence result [20]. Byrd et al. [11] develop a stochastic quasi-Newton algorithm that avoids the potentially harmful e ects of WebIn fact, the Newton or quasi-newton (QN) methods leveraging the second-order information are able to achieve a better solution than the first-order methods. Thus, …
