Deterministic Denominator Design for Localized Tamed Stochastic Gradient Langevin Dynamics
Yiwei Zhou, Ziheng Chen
If the denominator in a tamed stochastic gradient Langevin update uses the current stochastic-gradient draw, the conditional mean can be biased even when the stochastic-gradient or…

Novel physical property preserved methods for stochastic Schrödinger--KdV equation
Ziheng Chen, Jialin Hong, Liying Sun
In this work, we study the stochastic Schrödinger--KdV equation driven by additive noise from both analytical and numerical viewpoints. We first establish the evolution laws for t…
