Statistical Guarantees for Link Prediction using Graph Neural Networks

no code implementations5 Feb 2024 Alan Chung, Amin Saberi, Morgane Austern

This paper derives statistical guarantees for the performance of Graph Neural Networks (GNNs) in link prediction tasks on graphs generated by a graphon.

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.

Locality-Aware Graph-Rewiring in GNNs

no code implementations2 Oct 2023 Federico Barbero, Ameya Velingker, Amin Saberi, Michael Bronstein, Francesco Di Giovanni

Graph Neural Networks (GNNs) are popular models for machine learning on graphs that typically follow the message-passing paradigm, whereby the feature of a node is updated recursively upon aggregating information over its neighbors.

Online Stochastic Max-Weight Bipartite Matching: Beyond Prophet Inequalities

no code implementations20 Feb 2021 Christos Papadimitriou, Tristan Pollner, Amin Saberi, David Wajc

This is the best possible ratio for this problem, as it generalizes the original single-item prophet inequality problem.

Sampling Arborescences in Parallel

no code implementations17 Dec 2020 Nima Anari, Nathan Hu, Amin Saberi, Aaron Schild

For several well-studied combinatorial structures, counting can be reduced to the computation of a determinant, which is known to be in NC [Csa75].

Maximum Weight Online Matching with Deadlines

1 code implementation9 Aug 2018 Itai Ashlagi, Maximilien Burq, Chinmoy Dutta, Patrick Jaillet, Amin Saberi, Chris Sholley

We study the problem of matching agents who arrive at a marketplace over time and leave after d time periods.
