what is the difference between Association rule mining & frequent itemset mining

Question

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

My questio

Answer 1

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.
