no code implementations6 Oct 2023 Franka Bause, Samir Moustafa, Johannes Langguth, Wilfried N. Gansterer, Nils M. Kriege

Message passing neural networks iteratively generate node embeddings by aggregating information from neighboring nodes.

Gradual Weisfeiler-Leman: Slow and Steady Wins the Race

1 code implementation19 Sep 2022 Franka Bause, Nils M. Kriege

The classical Weisfeiler-Leman algorithm aka color refinement is fundamental for graph learning with kernels and neural networks.

A Temporal Graphlet Kernel for Classifying Dissemination in Evolving Networks

1 code implementation12 Sep 2022 Lutz Oettershagen, Nils M. Kriege, Claude Jordan, Petra Mutzel

We introduce the \emph{temporal graphlet kernel} for classifying dissemination processes in labeled temporal graphs.

Weisfeiler and Leman Go Walking: Random Walk Kernels Revisited

1 code implementation22 May 2022 Nils M. Kriege

Random walk kernels have been introduced in seminal work on graph learning and were later largely superseded by kernels based on the Weisfeiler-Leman test for graph isomorphism.

Temporal Walk Centrality: Ranking Nodes in Evolving Networks

1 code implementation8 Feb 2022 Lutz Oettershagen, Petra Mutzel, Nils M. Kriege

We propose the Temporal Walk Centrality, which quantifies the importance of a node by measuring its ability to obtain and distribute information in a temporal network.

Weisfeiler and Leman go Machine Learning: The Story so far

no code implementations18 Dec 2021 Christopher Morris, Yaron Lipman, Haggai Maron, Bastian Rieck, Nils M. Kriege, Martin Grohe, Matthias Fey, Karsten Borgwardt

In recent years, algorithms and neural architectures based on the Weisfeiler--Leman algorithm, a well-known heuristic for the graph isomorphism problem, have emerged as a powerful tool for machine learning with graphs and relational data.

Deep Weisfeiler-Lehman Assignment Kernels via Multiple Kernel Learning

no code implementations19 Aug 2019 Nils M. Kriege

Assignment kernels are based on an optimal bijection between the parts and have proven to be an effective alternative to the established convolution kernels.

A Survey on Graph Kernels

no code implementations28 Mar 2019 Nils M. Kriege, Fredrik D. Johansson, Christopher Morris

Graph kernels have become an established and widely-used technique for solving classification tasks on graphs.

Computing Optimal Assignments in Linear Time for Approximate Graph Matching

no code implementations29 Jan 2019 Nils M. Kriege, Pierre-Louis Giscard, Franka Bause, Richard C. Wilson

In this paper, we develop an algorithm which can find an optimal assignment in linear time when the cost function between objects is represented by a tree distance.

Recognizing Cuneiform Signs Using Graph Based Methods

no code implementations16 Feb 2018 Nils M. Kriege, Matthias Fey, Denis Fisseler, Petra Mutzel, Frank Weichert

To this end, the distance measure is used to implement a nearest neighbor classifier leading to a high computational cost for the prediction phase with increasing training set size.

A Unifying View of Explicit and Implicit Feature Maps of Graph Kernels

no code implementations2 Mar 2017 Nils M. Kriege, Marion Neumann, Christopher Morris, Kristian Kersting, Petra Mutzel

On this basis we propose exact and approximative feature maps for widely used graph kernels based on the kernel trick.

Faster Kernels for Graphs with Continuous Attributes via Hashing

no code implementations1 Oct 2016 Christopher Morris, Nils M. Kriege, Kristian Kersting, Petra Mutzel

While state-of-the-art kernels for graphs with discrete labels scale well to graphs with thousands of nodes, the few existing kernels for graphs with continuous attributes, unfortunately, do not scale well.
