Selecting Walk Schemes for Database Embedding

no code implementations20 Jan 2024 Yuval Lev Lubarsky, Jan Tönshoff, Martin Grohe, Benny Kimelfeld

We study the embedding of the tuples of a relational database, where existing techniques are often based on optimization tasks over a collection of random walks from the database.

Where Did the Gap Go? Reassessing the Long-Range Graph Benchmark

1 code implementation1 Sep 2023 Jan Tönshoff, Martin Ritzert, Eran Rosenbluth, Martin Grohe

The recent Long-Range Graph Benchmark (LRGB, Dwivedi et al. 2022) introduced a set of graph learning tasks strongly dependent on long-range interaction between vertices.

WL meet VC

1 code implementation26 Jan 2023 Christopher Morris, Floris Geerts, Jan Tönshoff, Martin Grohe

Secondly, when an upper bound on the graphs' order is known, we show a tight connection between the number of graphs distinguishable by the $1\text{-}\mathsf{WL}$ and GNNs' VC dimension.

One Model, Any CSP: Graph Neural Networks as Fast Global Search Heuristics for Constraint Satisfaction

1 code implementation22 Aug 2022 Jan Tönshoff, Berke Kisin, Jakob Lindner, Martin Grohe

We propose a universal Graph Neural Network architecture which can be trained as an end-2-end search heuristic for any Constraint Satisfaction Problem (CSP).

Walking Out of the Weisfeiler Leman Hierarchy: Graph Learning Beyond Message Passing

1 code implementation17 Feb 2021 Jan Tönshoff, Martin Ritzert, Hinrikus Wolf, Martin Grohe

As the theoretical basis for our approach, we prove a theorem stating that the expressiveness of CRaWl is incomparable with that of the Weisfeiler Leman algorithm and hence with graph neural networks.
