Point-PRC: A Prompt Learning Based Regulation Framework for Generalizable Point Cloud Analysis Hongyu Sun

Neural Information Processing Systems

Recent works demonstrate the performances of 3D point cloud recognition can be boosted remarkably by parameter-efficient prompt tuning. However, we observe that the improvement on downstream tasks comes at the expense of a severe drop in 3D domain generalization.

DropEdge not Foolproof: Effective Augmentation Method for Signed Graph Neural Networks

Neural Information Processing Systems

Signed graphs can model friendly or antagonistic relations where edges are annotated with a positive or negative sign. Signed Graph Neural Networks (SGNNs) have been widely used for signed graph representation learning. While significant progress has been made in SGNNs research, two issues (i.e., graph sparsity and unbalanced triangles) persist in the current SGNN models. We aim to alleviate these issues through data augmentation ( DA) techniques which have demonstrated effectiveness in improving the performance of graph neural networks. However, most graph augmentation methods are primarily aimed at graph-level and node-level tasks (e.g., graph classification and node classification) and cannot be directly applied to signed graphs due to the lack of side information (e.g., node features and label information) in available real-world signed graph datasets. Random DropEdge is one of the few DA methods that can be directly used for signed graph data augmentation, but its effectiveness is still unknown.
