The Apriori algorithm is a data mining algorithm that discovers frequent itemsets in a dataset. It is a simple and efficient algorithm that can be used to find patterns in data that would otherwise be difficult or impossible to find by hand. Apriori is often used in market basket analysis, but it can also be used in other applications, such as fraud detection and web mining.
Apriori works by iteratively generating candidate itemsets and then testing them against the data to see if they are frequent. A candidate itemset is a set of items that may be frequent. To generate candidate itemsets, Apriori starts with all of the single-item itemsets in the data. Then, it generates all of the two-item itemsets from the single-item itemsets. It continues this process until it has generated all of the candidate itemsets of the desired size.
Once Apriori has generated all of the candidate itemsets, it tests them against the data to see if they are frequent. A candidate itemset is frequent if it appears in a sufficient number of transactions in the data. The minimum number of transactions that a candidate itemset must appear in to be considered frequent is called the support threshold.
Apriori is a versatile algorithm that can be used in a variety of applications. Some of the most common applications of Apriori include:
