Improved convergence rates of nonparametric penalized regression under misspecified total variation

Marlena S. Bannick, Noah Simon

Penalties that induce smoothness are common in nonparametric regression. In many settings, the amount of smoothness in the data generating function will not be known. Simon and Sho…

A framework for leveraging machine learning tools to estimate personalized survival curves

Charles J. Wolock, Peter B. Gilbert, Noah Simon +1

The conditional survival function of a time-to-event outcome subject to censoring and truncation is a common target of estimation in survival analysis. This parameter may be of sci…

Regression in Tensor Product Spaces by the Method of Sieves

Tianyu Zhang, Noah Simon

Estimation of a conditional mean (linking a set of features to an outcome of interest) is a fundamental statistical task. While there is an appeal to flexible nonparametric procedu…

Mesh-Based Solutions for Nonparametric Penalized Regression

Brayan Ortiz, Noah Simon

It is often of interest to estimate regression functions non-parametrically. Penalized regression (PR) is one statistically-effective, well-studied solution to this problem. Unfort…

On the Optimality of Nuclear-norm-based Matrix Completion for Problems with Smooth Non-linear Structure

Yunhua Xiang, Tianyu Zhang, Xu Wang +2

Originally developed for imputing missing entries in low rank, or approximately low rank matrices, matrix completion has proven widely effective in many problems where there is no…

A Sieve Stochastic Gradient Descent Estimator for Online Nonparametric Regression in Sobolev ellipsoids

Tianyu Zhang, Noah Simon

The goal of regression is to recover an unknown underlying function that best links a set of predictors to an outcome from noisy observations. In nonparametric regression, one assu…
