Optimal Convergence for Stochastic Optimization with Multiple Expectation Constraints
Kinjal Basu, Preetam Nandy
In this paper, we focus on the problem of stochastic optimization where the objective function can be written as an expectation function over a closed convex set. We also consider…

Large-Sample Theory for the Bergsma-Dassios Sign Covariance
Preetam Nandy, Luca Weihs, Mathias Drton
The Bergsma-Dassios sign covariance is a recently proposed extension of Kendall's tau. In contrast to tau or also Spearman's rho, the new sign covariance vanishes if and only…

High-dimensional consistency in score-based and hybrid structure learning
Preetam Nandy, Alain Hauser, Marloes H. Maathuis
Main approaches for learning Bayesian networks can be classified as constraint-based, score-based or hybrid methods. Although high-dimensional consistency results are available for…
