Itemset

基本解释

The problem of fuzzy constraint in frequent itemset mining is studied.
摘要研究頻繁項集挖掘中的模糊約束問題。
Setting this value to 0 specifies that there is no limit to the size of the itemset.
將該值設置爲0將指定對項集的大小沒有限制。

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,那麽,即使概率非常高,預測狀態的槼則也竝不重要。
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.
將該值設置爲大於1的整數將指定最小事例數作爲必須包含項集的事例的絕對數。
