Summary: This paper proposes a novel method called DGS-MGNN, which utilizes a dynamic global structure enhanced multi-channel graph neural network to learn accurate representations of items. The method dynamically generates local, global, and consensus graphs using a multi-channel graph neural network, and learns more informative item representations based on the corresponding graph. In addition, the graph structure is used to assist the attention mechanism in filtering noisy information within sessions, resulting in an accurate intention representation for the user. Finally, a more accurate prediction probability distribution is generated by combining a repeat and explore module.

Summary: This paper proposes a pluggable framework called Adversarial Information Completion Graph Neural Networks (AIC-GNN) to address the problem of low-degree node representation learning. A novel Graph Information Generator is introduced to adaptively fit the node missing information distribution, and adversarial training is used to enhance the representational capacity of the model. Extensive experiments demonstrate the superior performance of AIC-GNN compared to state-of-the-art methods on four real-world graphs.

Summary: This paper addresses the vulnerability of graph neural networks to adversarial attacks and proposes an attack model based on the identical distribution hypothesis to address the issue of distribution consistency between training and test sets. The paper also analyzes the problem of graph poisoning attacks, derives the influence of perturbations in the training set on the test set, and delimits the feasible region of the attack. Numerical examples and experimental results validate the correctness of the attack gradient and the reasonableness and effectiveness of the proposed method.

Summary: This paper proposes a new social recommendation system called SocialLGN, which addresses the challenges of accurately learning user and item representations from user-item interaction graphs and social graphs, as well as integrating user representations learned from these two graphs. Experimental results demonstrate the superiority of SocialLGN, especially in handling the cold-start problem.

Summary: This paper proposes adaptive graph convolutional collaboration networks (AGCCNs) for semi-supervised classification of non-Euclidean data. AGCCNs utilize semantic information from different convolution layers and an attention mechanism to learn robust deep semantic features, addressing issues in traditional GCNs and achieving superior results compared to traditional GCNs in experimental evaluations.

Summary: The proposed mixed-order graph convolutional networks (MOGCN) address the oversmoothing issue and underutilization of pseudo-labels of unlabeled nodes in semi-supervised learning. MOGCN consists of two modules: constructing multiple GCN learners with multi-order adjacency matrices and employing a novel ensemble module to efficiently combine results from these learners. Experimental results on three public benchmark datasets demonstrate that MOGCN consistently outperforms state-of-the-art methods.
