WebWe derive a second-order ordinary differential equation (ODE) which is the limit of Nesterov's accelerated gradient method. This ODE exhibits approximate equivalence to Nesterov's scheme and thus can serve as a tool for analysis. We show that the continuous time ODE allows for a better understanding of Nesterov's scheme.
Web3.1 Nesterov’s Accelerated Gradient Descent Method Nesterov’s accelerated gradient descent methods have been used widely for solving smooth opti-mization problem. Consider the following optimization problem min x2 f(x) (8) where f(x) is a convex and L-smooth function. There are several variants of Nesterov’s accelerated gradient methods.
