In spite of the intensive research and development in this area, there does not exist a systematic treatment to introduce the fundamental concepts and recent progresses on machine learning algorithms, especially on those based on stochastic optimization methods, randomized algorithms, nonconvex ...
Convergence analysis of accelerated first-order methods for convex optimization problems are developed from the point of view of ordinary differential equation solvers. A new dynamical system, called Nesterov accelerated gradient (NAG) flow, is derived from the connection between acceleration mechanism and...
首先是first order methods在online learning中的自然应用,比如我们的问题改变定义,即我们在每个时间t,都有一个adversary选择一个f_t(\cdot)并report它在x_t的(sub)gradient给我们。那么显然我们的算法可以直接用来进行"learning",我们的regret是\sum_{t=1}^T f_t(x_t)- \sum_{t=1}^T f_t(x^*)(...

We introduce a generic scheme for accelerating first-order optimization methods in the sense of Nesterov, which builds upon a new analysis of the accelerated proximal point algorithm. Our approach consists of minimizing a convex objective by approximately solving a sequence of well-chosen ...
In this paper we propose and analyze two dual methods based on inexact gradient information and averaging that generate approximate primal solutions for smooth convex optimization problems. The complicating constraints are moved into the cost using the Lagrange multipliers. The dual problem is solved by...
