Off-policy evaluation (OPE) aims to estimate the performance of hypothetical policies using data generated by a different policy. Because of its huge potential impact in practice, there has been growing research interest in this field. There is, however, no real-world public dataset that enables the evaluation of OPE, making its experimental studies unrealistic and irreproducible. With the goal of enabling realistic and reproducible OPE research, we present Open Bandit Dataset, a public logged bandit dataset collected on a large-scale fashion e-commerce platform, ZOZOTOWN. Our dataset is unique in that it contains a set of multiple logged bandit datasets collected by running different policies on the same platform. This enables experimental comparisons of different OPE estimators for the first time. We also develop Python software called Open Bandit Pipeline to streamline and standardize the implementation of batch bandit algorithms and OPE. Our open data and software will contribute to fair and transparent OPE research and help the community identify fruitful research directions. We provide extensive benchmark experiments of existing OPE estimators using our dataset and software. The results open up essential challenges and new avenues for future OPE research.

    cs.SE 2025-11 conditional novelty 5.0 of 10

    A benchmark and small-scale evaluation suggesting LLM agents can modify off-policy evaluation code and sometimes improve the measured metrics, with the authors' two-agent framework the most reliable of those tested.

  7. Off-Policy Evaluation of Ranking Policies via Embedding-Space User Behavior Modeling

    stat.ML 2025-05 reject novelty 5.0 of 10

    The paper claims a new family of embedding-based off-policy estimators for ranking policies, but its central unbiasedness theorem is false under the stated assumptions.

  8. Quick-Draw Bandits: Quickly Optimizing in Nonstationary Environments with Extremely Many Arms

    cs.LG 2025-05 reject novelty 5.0 of 10

    Quick-Draw is a fast kernel-interpolation UCB bandit for large-arm nonstationary problems, but the claimed O*(sqrt T) regret bound does not follow from the paper's theorem.

  9. Off-Policy Evaluation for Recommendations with Missing-Not-At-Random Rewards

    stat.ML 2025-02 conditional novelty 4.0 of 10

    Using both action-selection and reward-observation propensities gives an unbiased off-policy value estimator under position-based missingness and the no-direct-effect assumption.

  10. Off-Policy Evaluation and Counterfactual Methods in Dynamic Auction Environments

    cs.AI 2025-01 reject novelty 4.0 of 10

    Continuous off-policy estimators give directionally correct predictions of payment-policy performance in dynamic auctions, enabling counterfactual comparison and in-sample policy optimization from logged data.
