Association Rule learning is a key technique in data mining used to discover interesting relationships or "associations" among variables in large datasets. It is famously used for Market Basket Analysis, which helps retailers understand the purchase patterns of customers.

Support: A measure of how frequently an itemset appears in the dataset.
Confidence: A measure of how often the "if-then" statement is found to be true.
