arXiv:2412.08052v2 Announce Type: replace Abstract: Off-policy evaluation (OPE) is critical for applying contextual bandit algorithms to high-stakes decision-making settings such as healthcare, where new treatment policies must be evaluated prior to deployment. Unfortunately, OPE techniques are inherently limited by the breadth of the available data, which may not be sufficient to evaluate the performance of a new policy. Recent work attempts to improve dataset coverage by adding expert-annotated counterfactual samples. However, such annotations are often imperfect and can lead to worse estima
The increasing deployment of AI in high-stakes environments like healthcare necessitates robust evaluation methods, making advancements in off-policy evaluation critical.
This development improves the reliability and safety of applying AI to critical decision-making, directly impacting the trust and effectiveness of autonomous systems.
The ability to more accurately evaluate new AI policies with imperfect data mitigates risks and broadens the practical applicability of contextual bandit algorithms.
