The Optimization and Improvement of the Apriori Algorithm

2008 International Symposium on Intelligent Information Technology Application Workshops, 2008
Through the study of Apriori algorithm we discover two aspects that affect the efficiency of the algorithm. One is the frequent scanning database, the other is large scale of the candidate item sets. Therefore, IApriori algorithm is proposed that can reduce the times of scanning database, optimize the join procedure of frequent item sets generated in ...

Enhancing the Apriori Algorithm for Frequent Set Counting

2001
In this paper we propose DCP, a new algorithm for solv- ing the Frequent Set Counting problem, which enhances Apriori. Our goal was to optimize the initial iterations of Apriori, i.e. the most time consuming ones when datasets characterized by short or medium length frequent patterns are considered. The main improvements regard the use of an innovative

Apriori and Other Algorithms

2001
In this chapter, we review the main rule-mining algorithms proposed in the literature. We start with two early algorithms known as AIS [AIS93] and SETM [HS95]. Next, we present two important algorithms known as Apriori and AprioriTid [S96], [ASR94]. We finally complete the chapter with two algorithms recently proposed in [PCY97] and [BMUT97] .

The Research of Improved Apriori Algorithm

Applied Mechanics and Materials, 2012
The first step of the association rule mining algorithm Apriori generate a lot of candidate item sets which are not frequent item sets, and all of these item sets cost a lot of system spending. To solve this problem，this paper presents an improved algorithm based on Apriori algorithm to improve the Apriori pruning step.

An Improved Algorithm of Apriori

2009
This paper puts forward a kind of improved algorithm after analyzing the classical Apriori algorithm. Through scanning database only once, all transactions are transformed into components of a two-dimensional array. The algorithm becomes more practical by introducing weight.

The Research of Improved Apriori Algorithm

2013
According to the weakness of Apriori algorithm, such as too many scans of the database and vast candidate itemsets, this chapter proposes an improved Apriori algorithm which scans the database only once by using arrays to store data. In addition, the new algorithm sorts the frequent itemsets from small to large according to their supports before they ...

An Improved Apriori-Pro Algorithm

2018
An improved Apriori-Pro algorithm is proposed to solve the disadvantages of a large number of invalid candidate sets when mining association rules. The new algorithm adds the transaction label column in the item set list to calculate the support degree, and makes use of the difference of the transaction label column to determine whether the link ...
