Can Hybrid Geometric Scattering Networks Help Solve the Maximum Clique Problem?

1 code implementation3 Jun 2022 Yimeng Min, Frederik Wenkel, Michael Perlmutter, Guy Wolf

We propose a geometric scattering-based graph neural network (GNN) for approximating solutions of the NP-hard maximum clique (MC) problem.

Geometric Scattering Attention Networks

1 code implementation28 Oct 2020 Yimeng Min, Frederik Wenkel, Guy Wolf

Geometric scattering has recently gained recognition in graph representation learning, and recent work has shown that integrating scattering features in graph convolution networks (GCNs) can alleviate the typical oversmoothing of features in node representation learning.

Data-Driven Learning of Geometric Scattering Networks

no code implementations6 Oct 2020 Alexander Tong, Frederik Wenkel, Kincaid MacDonald, Smita Krishnaswamy, Guy Wolf

We propose a new graph neural network (GNN) module, based on relaxations of recently proposed geometric scattering transforms, which consist of a cascade of graph wavelet filters.

Overcoming Oversmoothness in Graph Convolutional Networks via Hybrid Scattering Networks

no code implementations22 Jan 2022 Frederik Wenkel, Yimeng Min, Matthew Hirn, Michael Perlmutter, Guy Wolf

We further introduce an attention framework that allows the model to locally attend over combined information from different filters at the node level.

On the Scalability of GNNs for Molecular Graphs

no code implementations17 Apr 2024 Maciej Sypetkowski, Frederik Wenkel, Farimah Poursafaei, Nia Dickson, Karush Suri, Philip Fradkin, Dominique Beaini

However, structure-based architectures such as Graph Neural Networks (GNNs) are yet to show the benefits of scale mainly due to the lower efficiency of sparse operations, large data requirements, and lack of clarity about the effectiveness of various architectures.
