Title: A speed restart scheme for first order dynamics bearing second order information in time and space

Abstract: We present two techniques that can help stabilize otherwise erratic inertial methods. Combined, they can enhance the performance of accelerated methods, especially for functions with quadratic growth, for which the rate of linear convergence is improved.
