Association Rules is a data mining method to find the relation between items called rules. Finding rules in the association method can be divided into two phases. The first phase is finding the frequent pattern which satisfies specified minimum frequent, and the second phase is finding strict rules from the frequent pattern which satisfy the minimum support and confidence. The main problem of Association Rules is based on the algorithm used, and this method takes a large amount of memory and time-consuming. This study aims to add preprocessing using the aggregate function on the Apriori Algorithm and therefore improve the memory and time consumption for finding a large number of rules.
An Improved Frequent Pattern Tree Based Association Rule Mining Technique
2011 International Conference on Information Science and Applications, 2011
Discovery of association rules among the large number of item sets is considered as an important aspect of data mining. The ever increasing demand of finding pattern from large data enhances the association rule mining. Researchers developed a lot of algorithms and techniques for determining association rules. The main problem is the generation of candidate set. Among the existing techniques, the frequent pattern growth (FP-growth) method is the most efficient and scalable approach. It mines the frequent item set without candidate set generation. The main obstacle of FP growth is, it generates a massive number of conditional FP tree. In this research paper, we proposed a new and improved FP tree with a table and a new algorithm for mining association rules. This algorithm mines all possible frequent item set without generating the conditional FP tree. It also provides the frequency of frequent items, which is used to estimate the desired association rules.

Association rule mining is one of the important part in the field of data mining. The scope of association rule mining is very broad. In association rules mining, frequent item sets mining is essential. Apriori algorithm, Eclat algorithm and FP-growth algorithm are famous algorithms to find frequent item sets. This algorithm can reduce the database and improve mining efficiency.
Performance Analysis of Apriori and FP-Growth Algorithms ( Association Rule Mining ) 1

Association rule mining has become popular among marketers and organizations. In fact, an example of association rule mining is referred to as market basket analysis. The task is to find which items are frequently purchased together. This knowledge can be used by professionals to plan where to place items that are frequently bought together closely to each other, thus helping to improve the sales. It involves the relationships between items in a data set. Association rule mining finds out item sets which has minimum support and are represented in a relatively high number of transactions. These transactions are simply known as frequent item sets. The algorithms that use association rules are divided into two stages, first is to find the frequent sets and the second is to use these frequent sets to generate the association rules. In this paper we used Weka to compare two algorithms (Apriori and FP-growth) based on execution time and database scan parameters used are; number of instanc...

The effectiveness of mining association rules is a significant field of Knowledge Discovery in Databases (KDD). The Apriori algorithm is a classical algorithm in mining association rules. This paper presents an improved method for Apriori and Frequent Pattern algorithms to increase the efficiency of generating association rules. This algorithm adopts a new method to decrease the redundant generation of sub-itemsets during pruning the candidate itemsets, which can form directly the set of frequent itemset and remove candidates having a subset that is not frequent in the meantime. This algorithm can raise the probability of obtaining information in scanning database and reduce the potential scale of itemsets

In this paper we present new scheme for extracting association rules that considers the time, number of database scans, memory consumption, and the interestingness of the rules. Discover a FIS data mining association algorithm that removes the disadvantages of APRIORI algorithm and is efficient in terms of number of database scan and time. The frequent patterns algorithm without candidate generation eliminates the costly candidate generation. It also avoids scanning the database again and again. So, we use Frequent Pattern (FP) Growth ARM algorithm that is more efficient structure to mine patterns when database grows.

Data mining (DM) techniques is the set of algorithms that helps in extracting interesting patterns and previously unknown facts from larger volume of databases. Todays ever changing customer needs, fluctuation business market and large volume of data generated every second has generated the need of managing and analyzing such a large volume of data. Association Rule mining algorithms helps in identifying correlation between two different items purchased by an individual. Apriori Algorithm and FP-Growth Algorithm are the two algorithms for generating Association Rules. This paper aims at analyze the performance of Apriori and FP-Growth based on speed, efficacy and price and will help in understanding which algorithm is better for a particular situation. https://journalnx.com/journal-article/20150659
Analyzing Working of FP-Growth Algorithm for Frequent Pattern Mining
International Journal of Research Studies in Computer Science and Engineering, 2017
Frequent Itemset − It refers to a set of items that frequently appear together, for example, milk and bread. Frequent Subsequence − A sequence of patterns that occur frequently such as purchasing a camera is followed by the memory card. Frequent Sub Structure − Substructure refers to different structural forms, which may be combined with itemsets or subsequences. FP-Growth algorithm is the most popular algorithm for pattern mining. It is based on divide and conquer strategy. Compress the database providing frequent sets and divide this compressed database into a set of conditional databases, each related to a frequent set and apply data mining on each database. 2. DETAILED WORKING OF FP-GROWTH ALGORITHM The FP-Growth algorithm allows the discovery of frequent itemset without generating candidate itemset. It is a two-step approach mentioned as under [4, 5]. 1) Firstly a compact data structure is built which is referred as FP-tree. It is built using two passes over the data-set. 2) Traverse through FP-Tree and extract frequently occurring itemsets.

This paper presents a comparison between classical frequent pattern mining algorithms that use candidate set generation and test and the algorithms without candidate set generation. In order to have some experimental data to sustain this comparison a representative algorithm from both categories mentioned above was chosen (the Apriori, FP-growth and DynFP-growth algorithms). The compared algorithms are presented together with some experimental data that lead to the final conclusions.
