Genetic-fuzzy mining (GFM) was proposed to train fuzzy membership functions, thus enhancing the final solution quality. However, it is quite time-consuming because of frequent database scans for fitness evaluation. In this paper, we propose a parallel algorithm with MapReduce architecture to further speed up the genetic-fuzzy mining process. In the proposed approach, the master processor randomly...
In this paper, we propose an approach for mining both type-2 membership functions and fuzzy association rules. The 2-tuple linguistic representation is utilized to encode type-2 membership functions into chromosomes. After the genetic evolution, the tuned type-2 membership functions are used to induce fuzzy association rules. Experiments on a simulated dataset are made to show the merit of the proposed...
In the past, we proposed an algorithm for extracting appropriate multiple minimum support values, membership functions and fuzzy association rules from quantitative transactions. In this paper, an enhanced approach, called the fuzzy cluster-based genetic-fuzzy mining approach for items with multiple minimum supports (FCGFMMS), is proposed to speed up the evaluation process and keep nearly the same...
