A Graph Neural Network with Negative Message Passing for Graph Coloring

no code implementations26 Jan 2023 Xiangyu Wang, Xueming Yan, Yaochu Jin

In this paper, we propose a graph network model for graph coloring, which is a class of representative heterophilous problems.

End-to-End Pareto Set Prediction with Graph Neural Networks for Multi-objective Facility Location

no code implementations27 Oct 2022 Shiqing Liu, Xueming Yan, Yaochu Jin

The network outputs are then converted into the probability distribution of the Pareto set, from which a set of non-dominated solutions can be sampled non-autoregressively.
