Fake news detection on social media is crucial to purifying the online environment and protecting public safety. Many existing methods explore propagation structures through graph neural networks (GNNs) determine truthfulness of news. End-to-end supervised GNNs notoriously depend large amounts labels. Recently, self-supervised pretraining has been a promising solution alleviate dependence However, application in fake still suffers from two challenges: 1) missing unreliable interactions...

Denoising diffusion models have shown great potential in multiple research areas. Existing diffusion-based generative methods on de novo 3D molecule generation face two major challenges. Since majority heavy atoms molecules allow connections to through single bonds, solely using pair-wise distance model geometries is insufficient. Therefore, the first one involves proposing an effective neural network as denoising kernel that capable capture complex multi-body interatomic relationships and...

Next destination recommendation is a crucial research area for understanding human travel behavior. However, existing studies often overlook the problem of underfitting, which arises due to limited regularity in users' patterns. To tackle this issue, we leverage diverse co-occurrence patterns (CoPs) discover potential user preferences. These capture intersections with similar spatial and temporal characteristics travels. traditional graph neural network (GNN)-based approaches struggle...

Self-supervised learning (SSL) has become one of the most popular paradigms and achieved remarkable success in graph field. Recently, a series pre-training studies on heterogeneous graphs (HGs) using SSL have been proposed considering heterogeneity real-world data. However, verification robustness is still research gap. Most existing researches focus supervised attacks graphs, which are limited to specific scenario will not work when labels available. In this paper, we propose novel...
