KSD an Efficient Algorithm for Association Rule Mining (original) (raw)
Abstract — Data mining is an emerging field that comprises of various functions like classification, association rule mining, clustering, and outlier analysis. Association rule mining is a major, interesting and extremely studied function of data mining. Association rule mining identifies the correlation between different itemsets and find frequent and interesting rules. Frequent itemset mining is very common first step in considering datasets through wide range of applications. There have been proposed some methods in literature which scan database twice or more times to find approximate frequent patterns and frequent itemsets. Scanning database again and again makes mining process tedious and slow. The traditional approaches needs that every item in itemset happens in each supporting transaction. Yet the actual data has noise (meaningless data) and in existence of a noise, outdated itemset mining procedures might not be able to identify related frequent itemset(s). We have proposed a method in this paper that solved above mentioned problems. It scans database only once and makes mining fast and efficient. Our proposed method used technique named Fault Tolerance to handle noisy data and replaced database with a tree like structure. We are unaware of any technique yet introduced that can find approximate frequent itemset with only one scan of database. Further, our proposed method has an advantage on traditional Apriori and frequent pattern (FP) Tree) method as for as scanning and infrequent candidate generation are concerned. Keywords: Approximate pattern; frequent pattern; Apriori; fault tolerance; FP-Tree; FT-Apriori; AFI-FP

Survey on Incremental Association Rule Mining to Find Frequent Itemsets
2015
Mining frequent Itemsets has proved to be very difficult because of its computational complexity. But, , it has gained a lot of popularity due to the usefulness of association rules, despite having huge processing cost. This paper provides a comprehensive survey on the state-of-art algorithms for association rule mining, specially when the datasets used for rule mining are dynamic. When new data are added to a original dataset it may lead to additional rules or to modification of some existing rules. To find the association rules from the whole (old as well as new) dataset will be wastage of time only if the process is restarted from the beginning. Several algorithms have been developed to attend this important issue of the association rule mining problem. This paper analyzes some of the algorithms to tackle the incremental association rule mining problem.

2018
Today’s era is based on IT technologies, so data storage is increasing day by day. Result of that big amount of data stored in databases and warehouses. Therefore the Data mining becomes popular to explore and analyze the databases for finding the the interesting and unknown patterns and rules known as association rule mining. Association rule mining is one of the essential tasks of descriptive technique which can be found meaningful patterns from big collection of data. Mining frequent item set is basic principle of association rule mining. Many algorithms have been proposed from last many years including Efficient Mining of Frequent Item Sets on Large Uncertain Databases. An efficient Approach for the implementation of FP Tree computes the minimum-support for mining frequent patterns. Now a day, various techniques face the problem of data redundancy, candidate generation, memory consumption problem (FP-tree Algorithms) and other frequent patterns problem.

Association Rule Mining: Improved Tree-Based and Graph-Based Approach for Mining Frequent Item sets
Most of studies for mining frequent patterns are based on constructing tree for arranging the items to mine frequent patterns. Many algorithms proposed recently have been motivated by FP-Growth (Frequent Pattern Growth) process and uses an FP-Tree (Frequent Pattern Tree) to mine frequent patterns. In this paper we propose algorithm called FP-Growth-Graph and CATS Tree which uses graph and tree data structure to arrange the items for mining frequent item sets. CATS Tree extends the idea of FP Tree to improve storage compression and allow frequent pattern mining without generation of candidate itemsets.FP-Growth-Graph contain three main part, first is to scan the database only once ,the second is to prune non-frequent item and then construct FP-Graph.

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

International Journal of Scientific Research in Science, Engineering and Technology, 2020
Data mining turns into a tremendous territory of examination in recent years. A few investigates have been made in the field of information mining. The Association Rule Mining (ARM) is likewise an incomprehensible territory of exploration furthermore an information mining method. In this paper a study is done on the distinctive routines for ARM. In this paper the Apriori calculation is characterized and focal points and hindrances of Apriori calculation are examined. FP-Growth calculation is additionally talked about and focal points and inconveniences of FP-Growth are likewise examined. In Apriori incessant itemsets are created and afterward pruning on these itemsets is connected. In FP-Growth a FP-Tree is produced. The detriment of FP-Growth is that FP-Tree may not fit in memory. In this paper we have review different paper in light of mining of positive and negative affiliation rules.
IJERT-A Novel Association Rule Mining in Large Databases
International Journal of Engineering Research and Technology (IJERT), 2013
https://www.ijert.org/a-novel-association-rule-mining-in-large-databases https://www.ijert.org/research/a-novel-association-rule-mining-in-large-databases-IJERTV2IS3629.pdf One of the core topics of data mining is mining association rules in large databases. The correct and appropriate decision made by decision makers is the advantage in discovering these associations. The key process in association rule mining is discovering frequent item sets. Main challenges in developing association rules mining algorithms are the large number of rules generated that makes the algorithms inefficient and makes it complicated for end users to comprehend the generated rules. It is because of the many traditional association rule mining approaches adopt an iterative technique to discover association rule, which requires many calculations and a difficult transaction process. Furthermore, the existing mining Due to high and repeated disk access overhead the existing algorithms cannot perform efficiently. By keeping this thing in mind, in this paper we present a novel association rule mining approach that can efficiently find the association rules in large databases. By using the conventional Apriority approach with added features to improve data mining performance has been derived in the proposed approach. We have performed many experiments and differentiated the performance of our algorithm with existing algorithms found in the literature. Experimental results show that our approach can quickly and easily discover the frequent item sets and effectively mine potential association rules .
