Solving the accuracy-diversity dilemma via directed random walks
Jian-Guo Liu, Kerui Shi, Qiang Guo
Random walks have been successfully used to measure user or object similarities in collaborative filtering (CF) recommender systems, which is of high accuracy but low diversity. A…
Information filtering via biased heat conduction
Jian-Guo Liu, Tao Zhou, Qiang Guo
Heat conduction process has recently found its application in personalized recommendation [T. Zhou \emph{et al.}, PNAS 107, 4511 (2010)], which is of high diversity but low accurac…
Effect of user tastes on personalized recommendation
Jian-Guo Liu, Tao Zhou, Qiang Guo +2
In this paper, based on a weighted projection of the user-object bipartite network, we study the effects of user tastes on the mass-diffusion-based personalized recommendation algo…
Relationship Between Structural Characters and Synchronizability of Scale-free Networks
Jian-Guo Liu, Yan-Zhong Dang, Qiang Guo +1
Using Memory Tabu Search(MTS) algorithm, we investigate the relationship between structural characters and synchronizability of scale-free networks by maximizing and minimizing the…
