PartitionBlock Method of Feature Selection from Information System

  • Received Date: 16 Oct 2001
  • Publish Date: 31 Mar 2003
  • After utilizing the technique of the combination of And/Or Tree with Different Matrix(DM) and Minimum Different List(MDL), this paper presents a method called IBFS to compute a better feature selection from larger Information System(IS).IBFS mainly partitions larger IS into small ones(called identification block, IB) by the identification feature or features, and then computes the feature selections from IBs, finally forming a feature selection for IS. It has the advantage of high efficiency and determinacy.
