可积条件下偏微分方程EM算法的收敛速度

Convergence rate of EM algorithm for SDEs under integrability condition

Jianhai Bao, Xing Huang, Shao-Qin Zhang

摘要:

本文利用热核的Gauss型估计,建立了EM算法的Krylov估计和Khasminskill估计。作为应用,在考虑Zvonkin变换的条件下,我们研究了一类多维随机微分方程的EM算法在可积条件下的收敛速度,其中漂移不需要是分段Lipschitz的,并且在某种意义下更加奇异.

英文摘要:

In this paper, by employing Gaussian type estimate of heat kernel, we establish Krylov's estimate and Khasminskill's estimate for EM algorithm. As applications, by taking Zvonkin's transformation into account, we investigate convergence rate of EM algorithm for a class of multidimensional SDEs under integrability conditions, where the drifts need not to be piecewise Lipschitz and are much more singular in some sense.
