Efficiently Mining Maximal Frequent Itemsets
We present GenMax, a backtrack search based algorithm for mining maximal frequent itemsets. GenMax uses a number of optimizations to prune the search space. It uses a novel technique called progressive focusing to perform maximality checking, and diffset propagation to perform fast frequency computation. Systematic experimental comparison with previous work indicates that different methods have...
متن کاملAn Efficient Algorithm for Mining Maximal Frequent Item Sets
Problem Statement: In today’s life, the mining of frequent patterns is a basic problem in data mining applications. The algorithms which are used to generate these frequent patterns must perform efficiently. The objective was to propose an effective algorithm which generates frequent patterns in less time. Approach: We proposed an algorithm which was based on hashing technique and combines a ve...
متن کاملMining Maximal Frequent Subtrees based on Fusion Compression and FP-tree
It is commonly accepted that mining frequent subtrees play pivotal roles in areas like Web log analysis, XML document analysis, semi-structured data analysis, as well as biometric information analysis, chemical compound structure analysis, etc. An improved algorithm, i.e. MFPTM algorithm, which based on fusion compression and FP-tree principle, was proposed in this paper to determine a better w...
متن کاملMining Fuzzy Frequent Item Sets
Due to various reasons transaction data often lack information about some items. This leads to the problem that some potentially interesting frequent item sets cannot be discovered, since by exact matching the number of supporting transactions may be smaller than the user-specified minimum. In this study we try to find such frequent item sets nevertheless by inserting missing items into transac...
متن کاملImproved Maximal Length Frequent Item Set Mining
Association rule mining is one of the most important technique in data mining. Which wide range of applications It aims it searching for intersecting relationships among items in large data sets and discovers association rules. The important of association rule mining is increasing with the demand of finding frequent patterns from large data sources. The exploitation of frequent item set has be...
