Workshop overview: This workshop will be organized in two main components. The first component will provide a detailed description of the gradient descent algorithm and of the fast gradient algorithm developed by Nesterov in a landmark paper. We will emphasize the following central ideas that underlie these two algorithms: the choice of stepsize, the choice of momentum (for fast gradient), and a novel proof of their convergence properties based on the Fenchel conjugate.
