Nearly optimal central limit theorem and bootstrap approximations in high dimensions

no code implementations17 Dec 2020 Victor Chernozhukov, Denis Chetverikov, Yuta Koike

In this paper, we derive new, nearly optimal bounds for the Gaussian approximation to scaled averages of $n$ independent high-dimensional centered random vectors $X_1,\dots, X_n$ over the class of rectangles in the case when the covariance matrix of the scaled average is non-degenerate.

Adaptive deep learning for nonlinear time series models

no code implementations6 Jul 2022 Daisuke Kurisu, Riku Fukami, Yuta Koike

In this paper, we develop a general theory for adaptive nonparametric estimation of the mean function of a non-stationary and nonlinear time series model using deep neural networks (DNNs).
