i am new to data mining and confuse about Association rules and frequent item mining. for me i think both are same but i need views from experts on this forum
我的问题是
是关联规则挖掘与频繁的项目集挖掘?
谢谢
what is the difference between Association rule mining & frequent itemset mining?Thanks
推荐答案
关联规则类似于 A,B→ C,表示C倾向于当A和B发生时发生。一个项目集只是一个集合,例如 A,B,C,如果它的项目倾向于同时出现,那么这是很常见的。 是找到所有常见项目集,然后将它们后处理为规则。
An association rule is something like "A,B → C", meaning that C tends to occur when A and B occur. An itemset is just a collection such as "A,B,C", and it is frequent if its items tend to co-occur. The usual way to look for association rules is to find all frequent itemsets and then postprocess them into rules.
