Principal-Agent Reinforcement Learning

no code implementations25 Jul 2024 Dima Ivanov, Paul Dütting, Inbal Talgam-Cohen, Tonghan Wang, David C. Parkes

We model the delegated task as an MDP, and study a stochastic game between the principal and agent where the principal learns what contracts to use, and the agent learns an MDP policy in response.

Incentivizing Quality Text Generation via Statistical Contracts

1 code implementation17 Jun 2024 Eden Saig, Ohad Einav, Inbal Talgam-Cohen

While the success of large language models (LLMs) increases demand for machine-generated text, current pay-per-token pricing schemes create a misalignment of incentives known in economics as moral hazard: Text-generating agents have strong incentive to cut costs by preferring a cheaper model over the cutting-edge one, and this can be done "behind the scenes" since the agent performs inference internally.

Strategy-Proof Auctions through Conformal Prediction

no code implementations20 May 2024 Roy Maor Lotan, Inbal Talgam-Cohen, Yaniv Romano

The key novelties of our method are: (i) the formulation of a regret prediction model, used to quantify at test time violations of strategy-proofness; and (ii) an auction acceptance rule that leverages the predicted regret to ensure that for a new auction, the data-driven mechanism meets the strategy-proofness requirement with high probability (e. g., 99\%).

MAC Advice for Facility Location Mechanism Design

no code implementations18 Mar 2024 Zohar Barak, Anupam Gupta, Inbal Talgam-Cohen

We study the $k$-facility location mechanism design problem, where the $n$ agents are strategic and might misreport their location.

Contracting with a Learning Agent

no code implementations29 Jan 2024 Guru Guruganesh, Yoav Kolumbus, Jon Schneider, Inbal Talgam-Cohen, Emmanouil-Vasileios Vlatakis-Gkaragkounis, Joshua R. Wang, S. Matthew Weinberg

We initiate the study of repeated contracts with a learning agent, focusing on agents who achieve no-regret outcomes.

Delegated Classification

1 code implementation NeurIPS 2023 Eden Saig, Inbal Talgam-Cohen, Nir Rosenfeld

When machine learning is outsourced to a rational agent, conflicts of interest might arise and severely impact predictive performance.

Strategic Representation

no code implementations17 Jun 2022 Vineet Nair, Ganesh Ghalme, Inbal Talgam-Cohen, Nir Rosenfeld

In our main setting of interest, the system represents attributes of an item to the user, who then decides whether or not to consume.

Strategic Classification in the Dark

1 code implementation23 Feb 2021 Ganesh Ghalme, Vineet Nair, Itay Eilat, Inbal Talgam-Cohen, Nir Rosenfeld

Strategic classification studies the interaction between a classification rule and the strategic agents it governs.
