Clustering Weighted Slope One for distributed parallel computing
Xing Chen, Wang Hongfa · 2011
Slope One is a simple and widely used collective filter algorithm, it is easy to implemented and works effectively. After Slope One being published, some optimized Slope One algorithms were proposed for improving its accuracy, however these optimized algorithms still overlook some essential drawbacks of Slope One: oversize calculating set. This paper proposes an optimized Slope One which adapts clustering concept to conventional Slope One.
