  • Zhang, Huaifeng; Zhao, Yanchang; Cao, Longbing; Zhang, Chengqi (Springer, 2008)
    This paper proposes an algorithm to discover novel association rules, combined association rules. Compared with conventional association rule, this combined association rule allows users to perform actions directly. Combined ...
  • Zhao, Yanchang; Zhang, Huaifeng; Cao, Longbing; Zhang, Chengqi; Bohlscheid, Hans-Michael (Springer, 2008)
    Association mining often produces large collections of association rules that are difficult to understand and put into action. In this paper, we have designed a novel notion of combined patterns to extract useful and ...
  • Jia, Wenjing; Zhang, Huaifeng; Wu, Qiang; He, Sean (Image and Vision Computing New Zealand, 2007)
    This paper presents a method for vehicle number plate detection which combines edge and colour features of number plates. We concentrate on two key issues of this application: speed and robustness. Our focus is put on ...
  • Zhang, Huaifeng; Jia, Wenjing; Wu, Qiang; Hintz, Thomas; He, Sean (Image and Vision Computing New Zealand, 2007)
  • Zhong, Yunde; Zhang, Huaifeng (ACCV, 2002)
    The common practice to get more matching points between two perspective images proceeds from coarse matching to dense matching. However, in some applications, for example, in the visualization of point-based 3D ...
  • Zhao, Yanchang; Zhang, Huaifeng; Wu, Shan Shan; Pei, Jian; Cao, Longbing; Zhang, Chengqi; Bohlscheid, Hans-Michael (Springer, 2009)
    Debt detection is important for improving payment accuracy in social security. Since debt detection from customer transactional data can be generally modelled as a fraud detection problem, a straightforward solution is ...
  • Zhao, Yanchang; Zhang, Huaifeng; Cao, Longbing; Zhang, Chengqi; Bohlscheid, Hans-Michael (IEEE Computer Society, 2008)
    Traditional sequential pattern mining deals with positive sequential patterns only, that is, only frequent sequential patterns with the appearance of items are discovered. However, it is often interesting in many applications ...
  • Hintz, Thomas; Li, Jianmin; Zhang, Huaifeng; Wu, Qiang; Jia, Wenjing; He, Sean (CSREA Press, 2007)
  • Zhao, Yanchang; Zhang, Huaifeng; Cao, Longbing; Zhang, Chengqi; Bohlscheid, Hans-Michael (Springer, 2009)
    Traditional sequential pattern mining deals with positive correlation between sequential patterns only, without considering negative relationship between them. In this paper, we present a notion of impact-oriented negative ...
  • Zhao, Yanchang; Zhang, Huaifeng; Figueiredo, Fernando; Cao, Longbing; Zhang, Chengqi (ACM, 2007)
    Many organisations have their digital information stored in a distributed systems structure scheme, be it in different locations, using vertically and horizontally distributed repositories, which brings about an high level ...
