Reviews: DualDICE: Behavior-Agnostic Estimation of Discounted Stationary Distribution Corrections

NeurIPS 2019 Sun Dec 8th through Sat the 14th, 2019 at Vancouver Convention Center "1361" "DualDICE: Behavior-Agnostic Estimation of Discounted Stationary Distribution Corrections" Reviewer 1 Originality: I find this work to be original and the proposed algorithm to be novel. The authors clearly state what they contributions are and how their work differs itself from the prior works. Clarity/Quality: The paper is clearly written and is easy to follow, the authors do a great job stating the problem they consider, explaining existing solutions and their drawbacks, and then thoroughly building up the intuition behind their approach. Each theoretical step makes sense and is intuitive. I also appreciate the authors taking time to deriving their method using a simple convex function and then demonstrating that it is possible to extend the method to more general set of functions.
