矩阵分解模型在协同过滤算法中的作用

Role of Matrix Factorization Model in Collaborative Filtering Algorithm: A Survey

Dheeraj kumar Bokde, Sheetal Girase, Debajyoti Mukhopadhyay

摘要:

推荐系统应用信息检索技术来选择与给定用户相关的在线信息。协同过滤是目前应用最广泛的推荐系统构建方法。CF技术以用户项目评分的形式使用用户行为作为其用于预测的信息源。CF算法面临的主要挑战是评分矩阵的稀疏性和数据的增长性。矩阵分解很好地解决了这些挑战。在本文中,我们试图提出一个概述不同的MF模型的作用,以解决CF算法的挑战,这可以作为在这一领域的研究路线图。

英文摘要:

Recommendation Systems apply Information Retrieval techniques to select the online information relevant to a given user. Collaborative Filtering is currently most widely used approach to build Recommendation System. CF techniques uses the user behavior in form of user item ratings as their information source for prediction. There are major challenges like sparsity of rating matrix and growing nature of data which is faced by CF algorithms. These challenges are been well taken care by Matrix Factorization. In this paper we attempt to present an overview on the role of different MF model to address the challenges of CF algorithms, which can be served as a roadmap for research in this area.
