CoRe-GD: A Hierarchical Framework for Scalable Graph Visualization with GNNs

1 code implementation9 Feb 2024 Florian Grötschla, Joël Mathys, Robert Veres, Roger Wattenhofer

We introduce a scalable Graph Neural Network (GNN) based Graph Drawing framework with sub-quadratic runtime that can learn to optimize stress.

SURF: A Generalization Benchmark for GNNs Predicting Fluid Dynamics

1 code implementation30 Oct 2023 Stefan Künzli, Florian Grötschla, Joël Mathys, Roger Wattenhofer

We propose SURF, a benchmark designed to test the $\textit{generalization}$ of learned graph-based fluid simulators.

Flood and Echo Net: Algorithmically Aligned GNNs that Generalize

no code implementations10 Oct 2023 Joël Mathys, Florian Grötschla, Kalyan Varma Nadimpalli, Roger Wattenhofer

We test the Flood and Echo Net on a variety of synthetic tasks and the SALSA-CLRS benchmark and find that the algorithmic alignment of the execution improves generalization to larger graph sizes.

SALSA-CLRS: A Sparse and Scalable Benchmark for Algorithmic Reasoning

1 code implementation21 Sep 2023 Julian Minder, Florian Grötschla, Joël Mathys, Roger Wattenhofer

We introduce an extension to the CLRS algorithmic learning benchmark, prioritizing scalability and the utilization of sparse representations.

Abstract Visual Reasoning Enabled by Language

no code implementations7 Mar 2023 Giacomo Camposampiero, Loic Houmard, Benjamin Estermann, Joël Mathys, Roger Wattenhofer

While artificial intelligence (AI) models have achieved human or even superhuman performance in many well-defined applications, they still struggle to show signs of broad and flexible intelligence.

Learning Graph Algorithms With Recurrent Graph Neural Networks

1 code implementation9 Dec 2022 Florian Grötschla, Joël Mathys, Roger Wattenhofer

In order to scale, we focus on a recurrent architecture design that can learn simple graph problems end to end on smaller graphs and then extrapolate to larger instances.
