Optimal Demixing of Nonparametric Densities

Jianqing Fan, Zheng Tracy Ke, Zhaoyang Shi

Motivated by applications in statistics and machine learning, we consider a problem of unmixing convex combinations of nonparametric densities. Suppose we observe groups of sam…

Gaussian and Bootstrap Approximation for Matching-based Average Treatment Effect Estimators

Zhaoyang Shi, Chinmoy Bhattacharjee, Krishnakumar Balasubramanian +1

We establish Gaussian approximation bounds for covariate and rank-matching-based Average Treatment Effect (ATE) estimators. By analyzing these estimators through the lens of stabil…

Multivariate Gaussian Approximation for Random Forest via Region-based Stabilization

Zhaoyang Shi, Chinmoy Bhattacharjee, Krishnakumar Balasubramanian +1

We derive Gaussian approximation bounds for -Potential Nearest Neighbor (-PNN) based random forest predictions based on a set of training points given by a Poisson process un…

Nonsmooth Nonparametric Regression via Fractional Laplacian Eigenmaps

Zhaoyang Shi, Krishnakumar Balasubramanian, Wolfgang Polonik

We develop nonparametric regression methods for the case when the true regression function is not necessarily smooth. More specifically, our approach is using the fractional Laplac…

Adaptive and non-adaptive minimax rates for weighted Laplacian-eigenmap based nonparametric regression

Zhaoyang Shi, Krishnakumar Balasubramanian, Wolfgang Polonik

We show both adaptive and non-adaptive minimax rates of convergence for a family of weighted Laplacian-Eigenmap based nonparametric regression methods, when the true regression fun…
