Abstract:
A imm ing at the shortages o f d iscern ib ilitym a trix tha t conta ins null e lem ents and dup lica te e lem en ts, am ethod o f attr ibutes reduc tion based on bina ry discern ib ility m atr ix w as presented in this paper. It not on ly guarantees the integrity and accuracy of the attr ibutes reduction resu lts, but a lso cuts dow n the tim e and space o f the operation.
