Time-aware Collaborative Filtering with the Piecewise Decay Function
Pei Wu, Chi Ho Yeung, Weiping Liu +2
In this paper, we determine the appropriate decay function for item-based collaborative filtering (CF). Instead of intuitive deduction, we introduce the Similarity-Signal-to-Noise-…
Adaptive information filtering for dynamic recommender systems
Ci-Hang Jin, Jian-Guo Liu, Yi-Cheng Zhang +1
The dynamic environment in the real world calls for the adaptive techniques for information filtering, namely to provide real-time responses to the changes of system data. Where ma…
Collaborative filtering based on multi-channel diffusion
Ming-Sheng Shang, Ci-Hang Jin, Tao Zhou +1
In this paper, by applying a diffusion process, we propose a new index to quantify the similarity between two users in a user-object bipartite graph. To deal with the discrete rati…
