%X In this paper, the existing attribute reduction algorithms in rough sets are classified as members of TD-al-gorithms (Top Down); then a new reduction algorithm of BU(Bottom Up) is proposed; after the comparison to theideas of the two groups of reduction algorithms, an effective attribute reduction is created through adding proper localretrospect to the traditional methods; at last an experiment is given to show the validity of this new technique.
