Optimal Convergence for Stochastic Optimization with Multiple Expectation Constraints

no code implementations8 Jun 2019 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.

Personalized Treatment Selection using Causal Heterogeneity

1 code implementation29 Jan 2019 Ye Tu, Kinjal Basu, Cyrus DiCiccio, Romil Bansal, Preetam Nandy, Padmini Jaikumar, Shaunak Chatterjee

In this work, we develop a framework for personalization through (i) estimation of heterogeneous treatment effect at either a cohort or member-level, followed by (ii) selection of optimal treatment variants for cohorts (or members) obtained through (deterministic or stochastic) constrained optimization.

Inference for Individual Mediation Effects and Interventional Effects in Sparse High-Dimensional Causal Graphical Models

1 code implementation27 Sep 2018 Abhishek Chakrabortty, Preetam Nandy, Hongzhe Li

In particular, we assume that the causal structure of the treatment, the confounders, the potential mediators and the response is a (possibly unknown) directed acyclic graph (DAG).
