WebAug 6, 2016 · A rule is more general if it has the same RHS but one or more items removed from the LHS. Formally, a rule X -> Y is redundant if for some X' subset X, conf (X' -> Y) >= conf (X -> Y). This is equivalent to a negative or zero improvement as defined by Bayardo et … WebSep 1, 2024 · The strong association rule can be divided into effective and ineffective ones that can be measured by the lift degree. (3) L i f t (X ⇒ Y) = P (X ∪ Y) P (Y) In general, ifLift(X⇒Y) > 1, it belongs to the effective strong association rule. IfLift(X⇒Y) < 1, it is the … rocks off primal scream
