Title: A Speed Restarting scheme for a Dynamical System with Hessian-Driven Damping and Three Constant Coefficients

Abstract:

In this talk, we analyze a speed restarting scheme for the inertial system with three constant coefficients. We aim to establish a linear convergence rate for the function values along the restarted trajectories. The numerical experiments show that a dynamical system with constant coefficients and the speed restarting scheme together improve the performance of the dynamics. We also compare the speed restart scheme with other restart schemes for the corresponding iterative algorithms.
