neural graph collaborative filtering

We develop a new recommendation framework Neural Graph Collaborative Filtering (NGCF), which exploits the user-item graph structure by propagating embeddings on it. To solve the problem that collaborative filtering algorithm only uses the user-item rating matrix and does not consider semantic information, we proposed a novel collaborative filtering recommendation algorithm based on knowledge graph. 10/13/2020 ∙ by Esther Rodrigo Bonet, et al. for Collaborative Filtering ...

Authors: Esther Rodrigo Bonet, Duc Minh Nguyen, Nikos Deligiannis (Submitted on 13 Oct 2020) Abstract: Temporal collaborative filtering (TCF) methods aim at modelling non-static aspects behind recommender systems, such as the dynamics in users' preferences and social trends around items. We predict new adopters of specific items by proposing S-NGCF, a socially-aware neural graph collaborative filtering model. It indicates the node dropout ratio, which randomly blocks a particular node and discard all its outgoing messages.

Using the knowledge graph representation learning method, this method embeds the existing semantic data into a low-dimensional vector space. Subjects: Machine Learning, Information Retrieval. Graph-based collaborative filtering (CF) algorithms have gained increasing attention. This leads to the expressive modeling of high-order connectivity in user-item graph, effectively injecting the collaborative signal into the embedding process in an explicit manner. In Proc. In this paper, we propose a Unified Collaborative Filtering framework based on Graph Embeddings (UGrec for short) to solve the problem. It specifies the type of laplacian matrix where each entry defines the decay factor between two connected nodes. Despite the popularity of Collaborative Filtering (CF), CF-based methods are haunted by the cold-start problem, which has a signifi-cantly negative impact on users’ experiences with Recommender Systems (RS).

Graph Convolution Network (GCN) has become new state-of-the-art for collaborative filtering. If nothing happens, download GitHub Desktop and try again. Note that here we treat all unobserved interactions as the negative instances when reporting performance. We then use past ratings to construct a training set and learn to fill in the ratings that a given customer would give to products not yet rated. Usage. 5.4. Google Scholar Digital Library; Zhi-Dan Zhao and Ming-Sheng Shang. Specifically, UGrec models user and item interactions within a graph network, and sequential recommendation path is designed as a basic unit to capture the correlations between users and items. Existing neural collaborative filtering (NCF) recommendation methods suffer from severe sparsity problem.
