WebJan 1, 2011 · Finally, Nesterov's method (often called the Fast Gradient method) is given in Algorithm 1, where µ > 9 is the minimum eigenvalue of H. Note that due to the choice of the cost criterion, the matrix H is positive definite i.e. µ > 0. Nesterov's method uses the projected gradient step PU (v, h) and an additional "step" that leads to faster ... WebDec 13, 2011 · Fast Distributed Gradient Methods. We study distributed optimization problems when N nodes minimize the sum of their individual costs subject to a common vector variable. The costs are convex, have Lipschitz continuous gradient (with constant L), and bounded gradient. We propose two fast distributed gradient algorithms based on …
