Unbiased Estimation of the Value of an Optimized Policy

no code implementations7 Jun 2018 Elon Portugaly, Joseph J. Pfeiffer III

However, although A/B testing provides an unbiased estimator for the value of deploying B (i. e., switching from policy A to B), direct application of those samples to learn the the optimized policy P generally does not provide an unbiased estimator of the value of P as the samples were observed when constructing P. In situations where the cost and risks associated of deploying a policy are high, such an unbiased estimator is highly desirable.

Counterfactual Reasoning and Learning Systems

no code implementations11 Sep 2012 Léon Bottou, Jonas Peters, Joaquin Quiñonero-Candela, Denis X. Charles, D. Max Chickering, Elon Portugaly, Dipankar Ray, Patrice Simard, Ed Snelson

This work shows how to leverage causal inference to understand the behavior of complex learning systems interacting with their environment and predict the consequences of changes to the system.
