Hypergraph Node Classification With Graph Neural Networks

no code implementations8 Feb 2024 Bohan Tang, Zexi Liu, Keyue Jiang, Siheng Chen, Xiaowen Dong

However, in this paper, we theoretically demonstrate that, in the context of node classification, most HyperGNNs can be approximated using a GNN with a weighted clique expansion of the hypergraph.

Hypergraph Structure Inference From Data Under Smoothness Prior

no code implementations27 Aug 2023 Bohan Tang, Siheng Chen, Xiaowen Dong

However, existing methods either adopt simple pre-defined rules that fail to precisely capture the distribution of the potential hypergraph structure, or learn a mapping between hypergraph structures and node features but require a large amount of labelled data, i. e., pre-existing hypergraph structures, for training.

Learning Hypergraphs From Signals With Dual Smoothness Prior

no code implementations3 Nov 2022 Bohan Tang, Siheng Chen, Xiaowen Dong

Hypergraph structure learning, which aims to learn the hypergraph structures from the observed signals to capture the intrinsic high-order relationships among the entities, becomes crucial when a hypergraph topology is not readily available in the datasets.

Collaborative Uncertainty Benefits Multi-Agent Multi-Modal Trajectory Forecasting

Further, we apply the proposed framework to current SOTA multi-agent multi-modal forecasting systems as a plugin module, which enables the SOTA systems to 1) estimate the uncertainty in the multi-agent multi-modal trajectory forecasting task; 2) rank the multiple predictions and select the optimal one based on the estimated uncertainty.
