Being an important topic of the knowledge reduction of rough set, the reduction of the decision rules respectively eliminates the redundant attribute values of each decision rule based on rough logic. The definition of the binary discernibility matrix in the incomplete decision system was given by analyzing all kinds of definitions of the binary discernibility matrix. An algorithm for decision rules...
The FP-growth algorithm is a powerful algorithm to mine frequent patterns and it is non-candidate generation algorithm using a special structure FP-tree. Many algorithms proposed recently are based on FP-tree. These algorithms include all frequent itemsets mining, closed frequent itemsets mining and top-k closed frequent itemsets mining. However, it still requires two database scans, Although it is...
