Geometric Lattice Structure of Covering and Its Application to Attribute Reduction through Matroids
The reduction of covering decision systems is an important problem in data mining, and covering-based rough sets serve as an efficient technique to process the problem. Geometric lattices have been widely used in many fields, especially greedy algorithm design which plays an important role in the re...
