Data Mining By Parallelization of Fp-Growth AlgorithmIn this paper we present idea to make one main tree on master node and slave do processing with database rather than have multiple FP-trees, one for each processor Firstly, the dataset is divided equally among all participating processors Pi....

The GFP-Growth algorithm is designed to quickly mine a given set of item-sets using a small amount of memory. This paper proves that GFP-Growth yields the exact frequency-counts for each item-set of interest. It further shows that GFP-Growth can boost the performance for several problems ...
Algorithm 1: TD-FP-Growth Input: a transaction database, with items in each transaction sorted in the lexicographic order, a minimum support: minsup. Output: frequent patterns above the minimum support. Method: build the FP-tree; then call mine-tree ( ? , H); Procedure mine-tree(X, H)...
Data owners may be worried with the mistreatment of data in such situations. The privacy is not protected or preserve. Due to this reason they do not want their data to be mined particularly when these contain responsive information. Protect the data privacy in the route of data mining is ...
