5. Data Mining Concepts and Techniques
ABSTRACT
In this book the original Apriori algorithm is discussed. This algorithm uses prior knowledge of frequent itemset properties and employs an iterative approach using level wise search based on candidate generation. This technique is applied to a general data set of items. The input is a database of transactions containing items drawn from a set of items. Each transaction contains an itemset. The output of the algorithm is a set of itemsets that frequently occur in the input transactions.
