Itemset and rule
Itemset is simply a set of items, for example, {onions, potatoes, burger}. A rule consists of two itemsets, X and Y, in the following format:
X -> Y
This indicates a pattern that when the X itemset is observed, Y is also observed. To select interesting rules, various measures of significance can be used.
