The Impact of Algorithmic Risk Assessments on Human Predictions and its Analysis via Crowdsourcing Studies

1 code implementation3 Sep 2021 Riccardo Fogliato, Alexandra Chouldechova, Zachary Lipton

As algorithmic risk assessment instruments (RAIs) are increasingly adopted to assist decision makers, their predictive performance and potential to promote inequity have come under scrutiny.

How Transferable are the Representations Learned by Deep Q Agents?

no code implementations24 Feb 2020 Jacob Tyo, Zachary Lipton

In this paper, we consider the source of Deep Reinforcement Learning (DRL)'s sample complexity, asking how much derives from the requirement of learning useful representations of environment states and how much is due to the sample complexity of learning a policy.
