Rates of Estimation of Optimal Transport Maps using Plug-in Estimators via Barycentric Projections
Nabarun Deb, Promit Ghosal, Bodhisattva Sen
Optimal transport maps between two probability distributions and on have found extensive applications in both machine learning and statistics. In practice, t…
Detecting Structured Signals in Ising Models
Nabarun Deb, Rajarshi Mukherjee, Sumit Mukherjee +1
In this paper, we study the effect of dependence on detecting a class of signals in Ising models, where the signals are present in a structured way. Examples include Ising Models o…
Measuring Association on Topological Spaces Using Kernels and Geometric Graphs
Nabarun Deb, Promit Ghosal, Bodhisattva Sen
In this paper we propose and study a class of simple, nonparametric, yet interpretable measures of association between two random variables and taking values in general top…
Multivariate Rank-based Distribution-free Nonparametric Testing using Measure Transportation
Nabarun Deb, Bodhisattva Sen
In this paper, we propose a general framework for distribution-free nonparametric testing in multi-dimensions, based on a notion of multivariate ranks defined using the theory of m…
Two-component Mixture Model in the Presence of Covariates
Nabarun Deb, Sujayam Saha, Adityanand Guntuboyina +1
In this paper, we study a generalization of the two-groups model in the presence of covariates --- a problem that has recently received much attention in the statistical literature…
