Research of the Collaborative Filtering Algorithm for E-Commerce
In this paper we mainly discuss the Collaborative Filtering algorithm which is widely applied in E-commerce. This article presents the idea of Collaborative Filtering algorithm and its main step. It analyzes the problem of cold start and data sparsity which affect the accuracy of prediction and results, as well as an idea of improvement Collaborative Filtering algorithm.
