Distribution Estimation of Contaminated Data via DNN-based MoM-GANs
Fang Xie, Lihu Xu, Qiuran Yao +1
This paper studies the distribution estimation of contaminated data by the MoM-GAN method, which combines generative adversarial net (GAN) and median-of-mean (MoM) estimation. We u…
Distribution estimation and change-point estimation for time series via DNN-based GANs
Jianya Lu, Yingjun Mo, Zhijie Xiao +2
The generative adversarial networks (GANs) have recently been applied to estimating the distribution of independent and identically distributed data, and have attracted a lot of re…
Almost sure invariance principle of mixing time series in Hilbert space
Jianya Lu, Wei Biao Wu, Zhijie Xiao +1
Inspired by \citet{Berkes14} and \citet{Wu07}, we prove an almost sure invariance principle for stationary mixing stochastic processes defined on Hilbert space. Our result can…
An approximation to the invariant measure of the limiting diffusion of G/Ph/n+GI queues in the Halfin-Whitt regime and related asymptotics
Xinghu Jin, Guodong Pang, Lihu Xu +1
In this paper, we develop a stochastic algorithm based on the Euler--Maruyama scheme to approximate the invariant measure of the limiting multidimensional diffusion of …
Cramér-type moderate deviations for Euler-Maruyama scheme for SDE
Xiequan Fan, Haijuan Hu, Lihu Xu
In this paper, we establish normalized and self-normalized Cramér-type moderate deviations for Euler-Maruyama scheme for SDE. As a consequence of our results, Berry-Esseen's bounds…
Functional large deviations for Stroock's approximation to a class of Gaussian processes with application to small noise diffusions
Hui Jiang, Lihu Xu, Qingshan Yang
Letting~ be a standard Poisson process, Stroock~ \cite{Stroock-1981} constructed a family of continuous processes by $$Θ_ε(t)=\int_0^tθ_ε(r)dr, \ \ \…
