A Damped Newton Method Achieves Global and Local Quadratic Convergence Rate
Slavomír Hanzely, Dmitry Kamzolov, Dmitry Pasechnyuk +3
In this paper, we present the first stepsize schedule for Newton method resulting in fast global and local convergence guarantees. In particular, a) we prove an $O\left( \frac 1 {k…
Effects of momentum scaling for SGD
Dmitry A. Pasechnyuk, Alexander Gasnikov, Martin Takáč
The paper studies the properties of stochastic gradient methods with preconditioning. We focus on momentum updated preconditioners with momentum coefficient . Seeking to explain…
Stochastic optimization in digital pre-distortion of the signal
A. V. Alpatov, E. A. Peters, D. A. Pasechnyuk +1
In this paper, we test the performance of some modern stochastic optimization methods and practices in application to digital pre-distortion problem, that is a valuable part of pro…
