Leveraging Factored Action Spaces for Efficient Offline Reinforcement Learning in Healthcare

2 code implementations2 May 2023 Shengpu Tang, Maggie Makar, Michael W. Sjoding, Finale Doshi-Velez, Jenna Wiens

We study the theoretical properties of our approach, identifying scenarios where it is guaranteed to lead to zero bias when used to approximate the Q-function.

Disparate Censorship & Undertesting: A Source of Label Bias in Clinical Machine Learning

no code implementations1 Aug 2022 Trenton Chang, Michael W. Sjoding, Jenna Wiens

Using such biased labels in standard ML pipelines could contribute to gaps in model performance across patient groups.

Clinician-in-the-Loop Decision Making: Reinforcement Learning with Near-Optimal Set-Valued Policies

1 code implementation ICML 2020 Shengpu Tang, Aditya Modi, Michael W. Sjoding, Jenna Wiens

We analyze the theoretical properties of the proposed algorithm, providing optimality guarantees and demonstrate our approach on simulated environments and a real clinical task.
