A Local Graph Limits Perspective on Sampling-Based GNNs

no code implementations17 Oct 2023 Yeganeh Alimohammadi, Luana Ruiz, Amin Saberi

We propose a theoretical framework for training Graph Neural Networks (GNNs) on large input graphs via training on small, fixed-size sampled subgraphs.

Incentive Compatibility in the Auto-bidding World

no code implementations31 Jan 2023 Yeganeh Alimohammadi, Aranyak Mehta, Andres Perlroth

Through the analysis of this model, we uncover a surprising result: in auto-bidding with two advertisers, FPA and SPA are auction equivalent.

Fractionally Log-Concave and Sector-Stable Polynomials: Counting Planar Matchings and More

no code implementations4 Feb 2021 Yeganeh Alimohammadi, Nima Anari, Kirankumar Shiragur, Thuy-Duong Vuong

While perfect matchings on planar graphs can be counted exactly in polynomial time, counting non-perfect matchings was shown by [Jer87] to be #P-hard, who also raised the question of whether efficient approximate counting is possible.
