    Frequent pattern mining on stream data using Hadoop CanTree-GTree
    (2017) Kusumakumari, V.; Sherigar, D.; Chandran, R.; Patil, N.
    The need for knowledge discovery from real-time stream data is continuously increasing nowadays and processing of transactions for mining patterns needs efficient data structures and algorithms. We propose a time-efficient Hadoop CanTree-GTree algorithm, using Apache Hadoop. This algorithm mines the complete frequent item sets (patterns) from real time transactions, by utilizing the sliding window technique. These are used to mine for closed frequent item sets and then, association rules are derived. It makes use of two data structures - CanTree and GTree. The results show that the Hadoop implementation of the algorithm performs 5 times better than in Java. � 2017 The Author(s).
