Personalized Recommendation Algorithm of E-commerce Based on Cloud Computing-1

摘要

The project-based collaborative filtering algorithm and matrix decomposition-based ALS collaborative filtering algorithm in the personalized recommendation of e-commerce are analyzed deeply in the paper, the principles of parallelization work are discussed, and the parallelization processes of project-based collaborative filtering algorithm improvement and matrix decomposition-based ALS collaborative filtering algorithm are offered via using MapReduce parallel programming model.
