(F, epsilon)-Parallel Reducts in a Series of Decision Subsystems

In the paper we continue to investigate a new type of attribute reducts in a decision system, which is called parallel reduct. We extend the concept of parallel reducts to (F, epsilon)-parallel reducts and (F,k)-parallel reducts, and investigate their properties. Moreover, We present algorithms to get (F, epsilon)-parallel reducts and (F,k)-parallel reducts.
