https://en.wikipedia.org/wiki/Association_rule_learning
Association rules are usually required to satisfy a user-specified minimum support and a user-specified minimum confidence at the same time. Association rule generation is usually split up into two separate steps: A minimum support threshold is applied to find all frequent itemsets in a database.

Apriori is an algorithm for frequent item set mining and association rule learning over relational databases.It proceeds by identifying the frequent individual items in the database and extending them to larger and larger item sets as long as those item sets appear sufficiently often in the database.

This says how popular an itemset is, as measured by the proportion of transactions in which an itemset appears. ... One drawback of the confidence measure is that it might ...

Apriori calculates the probability of an item being present in a frequent itemset, given that another item or items is present. ... Minimum support and confidence are used to influence the build of an association model. Support and confidence are also the primary metrics for evaluating the quality of the rules generated by the model.
