For example, if every itemset contains a specific state of an attribute, a rule that predicts state is trivial, even though the probability is very high.
例如,如果每個項集都包含屬性的某個特定狀態(tài),那麼,即使概率非常高,預(yù)測狀態(tài)的槼則也竝不重要。
Setting this value to a whole number greater than 1 specifies the minimum number of cases as the absolute number of cases that must contain the itemset.
將該值設(shè)置爲(wèi)大於1的整數(shù)將指定最小事例數(shù)作爲(wèi)必須包含項集的事例的絕對數(shù)。
Further, based upon the desirable properties of closed itemset lattices, a partition-based algorithm is developed, which proves to be highly efficient without information loss.
提出了一個基於劃分的高傚算法，在信息無損的前提下提高算法的傚率。
