Performance Evaluation of Apriori Algorithm on a Hadoop Cluster

Frequent Itemset Mining is a well-known concept in data sciences. If we feed frequent itemset miner algorithms with large datasets they become resource hungry fast as their search space explodes. This problem is even more apparent when we try to use them on Big Data. Recent advances in parallel programming provides good solutions to deal with large datasets but they present their own problems w...

Research of Improved Apriori Algorithm Based on Itemset Array

Mining frequent item sets is a major key process in data mining research. Apriori and many improved algorithms are lowly efficient because they need scan database many times and storage transaction ID in memory, so time and space overhead is very high. Especially, they are lower efficient when they process large scale database. The main task of the improved algorithm is to reduce time and space...

An Efficient Implementation of Apriori Algorithm Based on Hadoop-mapreduce Model

Finding frequent itemsets is one of the most important fields of data mining. Apriori algorithm is the most established algorithm for finding frequent itemsets from a transactional dataset; however, it needs to scan the dataset many times and to generate many candidate itemsets. Unfortunately, when the dataset size is huge, both memory use and computational cost can still be very expensive. In ...

Research of Fast Search Algorithm Based on Hadoop Cloud Platform

Hadoop is a powerful open cloud computing platform, using MapReduce hardled data seg mentation and merging. Personal data in the flat without any protection, could be attacked at any time, as a result, cloud platform on the personal fast search algorithm problem is very important. In this paper, a Hadoop cloud data search platform to have safety rules was proposed, it increase the safety of the...
