摘要:

当用户连接到互联网来满足他的需求时,他经常会遇到大量的相关信息。推荐系统是一种对信息进行大规模过滤并提供用户满意和感兴趣的项目的技术。机器学习方法的进步,特别是深度学习,使得推荐系统取得了巨大的成就,尽管这些系统仍然受到诸如冷启动和稀疏性问题等挑战。为了解决这些问题,通常使用诸如用户通信网络的上下文信息。本文提出了一种基于矩阵分解和图分析的推荐方法。此外,我们利用深度自动编码器来初始化用户和项目的潜在因素,深度嵌入方法从用户信任图中收集用户的潜在因素。该方法在两个标准数据集上实现。实验结果和比较表明,该方法优于现有的国家的最先进的推荐方法。我们的方法优于其他比较方法,并取得了很大的改善。

英文摘要:

When a user connects to the Internet to fulfill his needs, he often encounters a huge amount of related information. Recommender systems are the techniques for massively filtering information and offering the items that users find them satisfying and interesting. The advances in machine learning methods, especially deep learning, have led to great achievements in recommender systems, although these systems still suffer from challenges such as cold-start and sparsity problems. To solve these problems, context information such as user communication network is usually used. In this paper, we have proposed a novel recommendation method based on Matrix Factorization and graph analysis methods. In addition, we leverage deep Autoencoders to initialize users and items latent factors, and deep embedding method gathers users' latent factors from the user trust graph. The proposed method is implemented on two standard datasets. The experimental results and comparisons demonstrate that the proposed approach is superior to the existing state-of-the-art recommendation methods. Our approach outperforms other comparative methods and achieves great improvements.
