Research and design of heuristic attribute reduction algorithm

Based on the attribute reduction of rough set, a new algorithm was proposed with two ways.By using binary discernibility matrix,attribute reduction set in the first step could be contributed.Then using recognizable matrix and its important attribute to get attribute reduction in the mean time this reduction is checking whether it is contained by the reduction set in the first step,so as to judge if this reduction set belongs to the feasible one.It's a kind of intuitionistic and effective attribute reduction algorithm with the demonstration of theoretical analysis and experiment.
