Counterfactual Learning with General Data-generating Policies

Yusuke Narita, Kyohei Okumura, Akihiro Shimizu +1

Off-policy evaluation (OPE) attempts to predict the performance of counterfactual policies using log data from a different policy. We extend its applicability by developing an OPE…

Doubly Robust Off-Policy Evaluation for Ranking Policies under the Cascade Behavior Model

Haruka Kiyohara, Yuta Saito, Tatsuya Matsuhiro +3

In real-world recommender systems and search engines, optimizing ranking decisions to present a ranked list of relevant items is critical. Off-policy evaluation (OPE) for ranking p…
