  1. Structured Rough Set Approximations

    Hu, MengjunFaculty of Graduate Studies and Research, University of Regina2014

    Rough set theory is widely used in many areas, such as artificial intelligence, machine learning and data mining. Lower and upper approximations are two fundamental notions for concept analysis with rough set theory. In rough set theory, one can obtain two kinds of sets in an information table, …

  2. Reducts and Rough Set Analysis

    Fu, RongFaculty of Graduate Studies and Research, University of Regina2012

    Rough set theory offers a mathematical approach to data analysis and data mining. It can be used to learn classification rules that define classes of a classi- fication based on some well defined concepts. The fundamental task of rough set data analysis is to precisely construct and interpret …

  11. Empirical analysis of rough set categorical clustering techniques based on rough purity and value set

    Uddin, JamalUniversiti Tun Hussein Onn Malaysia2017

    Clustering a set of objects into homogeneous groups is a fundamental operation in data mining. Recently, attention has been put on categorical data clustering, where data objects are made up of non-numerical attributes. The implementation of several existing categorical clustering techniques is …
