%X Upper approximation and lower approximation are the basic definitions in Rough Set Theory(RST),it makes vague boundary computable,however,none of existing definition of RST brings efficient way to compute boundary.Based on Bit Granular Computing,Granular Matrix and its operation were defined and GrC-based RST model was established to complete the basic definition and computation of RST.The new model builds theoretic foundations for GrC-based knowledge discovery algorithms.Furthermore,modified sufficient and...
