2022, Information SciencesCitation Excerpt :Covering-based rough sets [27] (CbRSs), as one of the essential extension model of classical rough sets [10], were presented to deal with covering data. From a theoretical perspective, nearly 40 pairs of covering approximation operators [2,32] have been established, corresponding axiomatic systems of them [26,28] have been established, and several types of covering reduction [23] have been defined. In application, they have been used to decision rule synthesis [3,19], attribute reduction [14,24,33], and any other fields [7,20,34].
