Apriori algorithm

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. Apriori algorithm is a classical algorithm in data mining. It is used for mining frequent itemsets and relevant association rules. It is devised to operate on a database containing a lot of transactions, for instance, items brought by customers in a store.

Name of the algorithm is . Read more to learn about its extensive use in data analysis especially in data mining. This article will provide you with a detailed knowledge of Apriori Algorithm used to find frequent itemset, how it works and the math behind it. The Apriori Algorithm is an influential algorithm for mining frequent itemsets for boolean association rules.

Different statistical algorithms have been developed to implement association rule mining, and Apriori is one such algorithm. This presentation explains about introduction and steps involved in Apriori Algorithm.
