<b>Abstract:</b> Nesterov’s accelerated gradient descent has played a key role
at the heart of optimization theory. While typically such accelerated
methods are considered in the context of first-order convex
optimization, it turns out that there is a natural extension to methods
based on higher-order derivative information. Recently, there has been
much additional work on such higher-order accelerated methods that,
under appropriate smoothness conditions, nearly match known lower
bounds. In this talk, I will discuss these advances in higher-order
acceleration, and I will further present recent work showing how such
methods can even lead to faster rates for some non-smooth optimization
problems.
