  • Enhancing grid-density based clustering for high dimensional data 
    Zhao Yanchang; Cao Jie; Zhang Chengqi; Zhang Shichao (Elsevier Inc., 2011)
    We propose an enhanced grid-density based approach for clustering high dimensional data. Our technique takes objects (or points) as atomic units in which the size requirement to cells is waived without losing clustering ...
  • Multi-sphere Support Vector Data for Outliers Detection on Multi-distribution Data 
    Xiao Yan Shan; Liu Bo; Cao Longbing; Wu Xindong; Zhang Chengqi; Hao Zhifeng; Cao Jie; Yang Fengzhao (IEEE Computer Society Press, 2009)
    SVDD has been proved a powerful tool for outlier detection. However, in detecting outliers on multi-distribution data, namely there are distinctive distributions in the data, it is very challenging for SVDD to generate a ...
