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-…
Dynamics underlying Box-office: Movie Competition on Recommender Systems
C. H. Yeung, G. Cimini, C. -H. Jin
We introduce a simple model to study movie competition in the recommender systems. Movies of heterogeneous quality compete against each other through viewers' reviews and generate…
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…
Effective and Efficient Similarity Index for Link Prediction of Complex Networks
Linyuan Lv, Ci-Hang Jin, Tao Zhou
Predictions of missing links of incomplete networks like protein-protein interaction networks or very likely but not yet existent links in evolutionary networks like friendship net…
