The Role of the Marketplace Operator in Inducing Competition

no code implementations9 Mar 2025 Tiffany Ding, Dominique Perrault-Joncas, Orit Ronen, Michael I. Jordan, Dirk Bergemann, Dean Foster, Omer Gottesman

The steady rise of e-commerce marketplaces underscores the need to study a market structure that captures the key features of this setting.

C-3DPO: Constrained Controlled Classification for Direct Preference Optimization

no code implementations22 Feb 2025 Kavosh Asadi, Julien Han, Xingzi Xu, Dominique Perrault-Joncas, Shoham Sabach, Karim Bouyarmane, Mohammad Ghavamzadeh

We then leverage this classification framework to demonstrate that the underlying problem solved in these algorithms is under-specified, making them susceptible to probability collapse of the winner-loser responses.

A shared-revenue Bertrand game

no code implementations11 Feb 2025 Raj Pabari, Udaya Ghai, Dominique Perrault-Joncas, Kari Torkkola, Orit Ronen, Dhruv Madeka, Dean Foster, Omer Gottesman

We introduce and analyze a variation of the Bertrand game in which the revenue is shared between two players.

Meta-Analysis of Randomized Experiments with Applications to Heavy-Tailed Response Data

no code implementations14 Dec 2021 Nilesh Tripuraneni, Dhruv Madeka, Dean Foster, Dominique Perrault-Joncas, Michael I. Jordan

The key insight of our procedure is that the noisy (but unbiased) difference-of-means estimate can be used as a ground truth ``label" on a portion of the RCT, to test the performance of an estimator trained on the other portion.

Improved graph Laplacian via geometric self-consistency

no code implementations NeurIPS 2017 Dominique Perrault-Joncas, Marina Meila

We address the problem of setting the kernel bandwidth used by Manifold Learning algorithms to construct the graph Laplacian.
