A Novel Density-Based methods GEP-Cluster Algorithm for Collaborative Filtering
Hong Guo Cai, Chang An Yuan · Applied Mechanics and Materials · 2013
To further solve the expansion performance problems of collaborative filtering technology. Firstly, form a few better center areas by using density partition and numerical distance between objects. Then, use the gene expression programming（GEP） to find the cluster centers. Propose a cluster algorithm of Density-based methods GEP-Cluster (DGEPC) to solve the nearest neighbor problem. Push the GEP technology for the Personalization Recommendation system.
