Exploiting Cross-session Information for Session-based Recommendation with Graph Neural Networks Published in TOIS, 2020. Data in social recommender systems can be represented as user-user social graph and user-item graph; and learning latent factors of users and items is the key. Deep Adversarial Canonical Correlation Analysis. In order to consider both interactions and opinions in the user-item graph, we introduce user aggregation, which is to aggregate users’ opinions in item modeling. In particular, we provide a principled approach to jointly capture interactions and opinions in the user-item graph and propose the framework GraphRec, which coherently models two graphs and heterogeneous strengths. For example, the user-item graph encodes both interactions and their associated opinions; social relations have heterogeneous strengths; users involve in two graphs (e.g., the user-user social graph and the user-item graph). Graph Neural Networks(GNN), a method based on deep learning that operates on graph domain, has received more and more attention recently. (Long Paper, Acceptance rate: 19%.) Graph neural network, as a powerful graph representation learning method, has been widely used in diverse scenarios, such as NLP, CV, and recommender systems.

To address the three aforementioned challenges simultaneously, in this paper, we present a novel graph neural network framework (GraphRec) for social recommendations. The need for new optimization methods and neural network architectures that can accommodate these relational and non-Euclidean structures is becoming increasingly clear. A Framework for Recommending Accurate and Diverse Items Using Bayesian Graph Convolutional Neural Networks We take a first step to introduce a principled way to model the uncertainty in the user-item interaction graph using the Bayesian Graph Convolutional Neural Networks framework. Original dataset is split into training, validation and testing dataset according to the rating timestamp of each user. Graph Neural Networks for Social Recommendation, WWW'19. Wenqi Fan, Yao Ma, Han Xu, Xiaorui Liu, Jianping Wang, Qing Li, and Jiliang Tang. [Arxiv], Wenqi Fan, Tyler Derr, Yao Ma, Jianping Wang, Jiliang Tang, Qing Li. In this paper, we propose an effective graph convolutional neural network based model, i.e., SocialGCN, for social recommendation. 2020. To model social homophily, Inf-VAE utilizes powerful graph neural network architectures to learn social variables that selectively exploit the social connections of users. The talk then shifts to talk about Graph Convolutions. In this talk, Bryan Perozzi presents an overview of Graph Embeddings and Graph Convolutions. The original version of this code base was from GraphSage. Google Scholar Digital Library; Wenqi Fan, Yao Ma, Qing Li, Yuan He, Eric Zhao, Jiliang Tang, and Dawei Yin.

These advantages of GNNs provide great potential to ad-vance social … If you use this code, please cite our paper: Raw Datasets (Ciao and Epinions) can be downloaded at http://www.cse.msu.edu/~tangjili/trust.html. For example, the user-item graph encodes both interactions and their associated opinions; social relations have heterogeneous strengths; users involve in two graphs (e.g., the user-user social graph and the user-item graph). Recommend one item to one user actually is the link prediction on the user-item graph. In many real-world applications, however, such long-term profiles often do not exist and recommendations therefore have to be made solely based on the observations of a user with the system during an ongoing session. The overall architecture of the proposed model. GNNs are neural networks that take graphs as inputs. The second component is item modeling, which is to learn latent factors of items. Ciao and Epinions Dataset can be available in dataset folder. These advantages of GNNs provide great potential to ad- vance social recommendation since data in social recommender systems can be represented as user-user social graph and user-item graph; and learning latent factors of users and items is the key. It contains two graphs including the user-item graph (left part) and the user-user social graph (right part). Wenqi Fan, Yao Ma, Dawei Yin, Jianping Wang, Jiliang Tang, Qing Li.
