Improving efficiency of apriori algorithm
Witryna1 gru 2012 · Apriori algorithm is widely adopted is association rule mining for generating closely related item sets. Traditional apriori algorithm is space and time consuming since it requires repeated scanning of whole transaction database. In this paper we propose improved apriori algorithm based on compressed transaction database. WitrynaUse the following methods to improve the efficiency of the apriori algorithm. Transaction Reduction – A transaction not containing any frequent k-itemset becomes useless in subsequent scans. Hash …
