A comparative study of multigranulation rough sets and concept lattices via rule acquisition

作者：

Highlights：

•

• Transforming decision systems into formal decision contexts is studied.

• Relationship between “AND” decision rules and granular rules is discussed.

• Relationship between “OR” decision rules and disjunctive rules is investigated.

• Support and certainty factors of different rules are compared.

• Algorithm complexity of rule acquisition is analyzed.
