A Direct Approach for Algebraic Reduction and Core Attributes based on D-S Evidence Theory[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2011,50(5):54-58.DOI:
the existing approaches based on D-S evidence theory have to transfer it into consistent one firstly and get a generalized decision reduction. However
the generalized decision reduction is different from algebraic one sometimes. It is proved that generalized decision reduction is just equivalent to assignment reduction whether the table consistent or inconsistent. Under D-S evidence theory
a new approach
which can directly get the algebraic reduction and core attributes for inconsistent decision table
is proposed and its correctness is illustrated with numerical example.
