Empirical Bayes mean estimation with nonparametric errors via order statistic regression on replicated data

2 code implementations14 Nov 2019 Nikolaos Ignatiadis, Sujayam Saha, Dennis L. Sun, Omkar Muralidharan

We study empirical Bayes estimation of the effect sizes of $N$ units from $K$ noisy observations on each unit.

Two-component Mixture Model in the Presence of Covariates

1 code implementation18 Oct 2018 Nabarun Deb, Sujayam Saha, Adityanand Guntuboyina, Bodhisattva Sen

We propose a tuning parameter-free nonparametric maximum likelihood approach, implementable via the EM algorithm, to estimate the unknown parameters.

On the nonparametric maximum likelihood estimator for Gaussian location mixture densities with application to Gaussian denoising

no code implementations6 Dec 2017 Sujayam Saha, Adityanand Guntuboyina

We study the Nonparametric Maximum Likelihood Estimator (NPMLE) for estimating Gaussian location mixture densities in $d$-dimensions from independent observations.

Sharp Inequalities for $f$-divergences

no code implementations2 Feb 2013 Adityanand Guntuboyina, Sujayam Saha, Geoffrey Schiebinger

$f$-divergences are a general class of divergences between probability measures which include as special cases many commonly used divergences in probability, mathematical statistics and information theory such as Kullback-Leibler divergence, chi-squared divergence, squared Hellinger distance, total variation distance etc.
