  • Yang, Jie; Xia, W.; Wang, Xiangyang; Jensen, Richard; Teng, X. (2007)
    We propose a new feature selection strategy based on rough sets and Particle Swarm Optimization (PSO). Rough sets has been used as a feature selection method with much success, but current hill-climbing rough set approaches ...
  • Shen, Qiang; Jensen, Richard (2009)
    The evaluation of glass evidence in forensic science is an important issue. Traditionally, this has depended on the comparison of the physical and chemical attributes of an unknown fragment with a control fragment. A high ...
  • Slezak, Dominik; Cornelis, Chris; Hurtado Martín, German; Jensen, Richard (2008-06-13)
    In this paper, within the context of fuzzy rough set theory, we generalize the classical rough set framework for data-based attribute selection and reduction, based on the notion of fuzzy decision reducts. Experimental ...

  • Jensen, Richard; Mac Parthaláin, Neil; Shen, Qiang (2008-07-03)
    Dataset dimensionality is undoubtedly the single most significant obstacle which exasperates any attempt to apply effective computational intelligence techniques to problem domains. In order to address this problem a ...

  • Verbiest, Nele; Cornelis, Chris; Jensen, Richard (IEEE Press, 2012)
    This paper proposes a classifier that uses fuzzy rough set theory to improve the Fuzzy Nearest Neighbour (FNN) classifier. We show that previous attempts to use fuzzy rough set theory to improve the FNN algorithm have some ...
  • Vander Heyden, Yvan; Dejaegher, Bieke; Jensen, Richard; Funar-Timofei, Simona; Goodarzi, Mohammad (2011-07-13)
    In cancer chemotherapy, multidrug resistance (MDR) is a major clinical problem which occurs by an influential mechanism and which leads to the failure of cancer chemotherapy and/or a relapse of the cancer. In this study, ...

    The accuracy of methods for the assessment of mammographic risk analysis is heavily related to breast tissue characteristics. Previous work has demonstrated considerable success in developing an automatic breast tissue ...
  • Jensen, Richard; Shen, Qiang (2004)
    Due to the explosive growth of electronically stored information, automatic methods must be developed to aid users in maintaining and using this abundance of information effectively. In particular, the sheer volume of ...

  • MacParthalain, Neil; Jensen, Richard (IEEE Press, 2015)
    Much use has been made of particle swarm optimisation as a tool to solve complex optimisation tasks, and many extensions and modifications to the original algorithm have been proposed. One such extension is related to the ...
