Fuzzy Clustering for Missing Data Based on Particle Swarm Optimization and Artificial Bee Colony Algorithm
The existing fuzzy clustering don’t effectively dispose the missing data, and proposes a fuzzy clustering approach for missing data based on Particle Swarm Optimization and Artificial Bee Colony Algorithm (PSOABC-FC). Use the interval to process missing data by searching the nearest samples, so the traditional fuzzy clustering method can cope with missing data. Divide the population into two subgroup. Subgroup one use the particle swarm optimization method to search, and Subgroup two use the artificial bee colony. In order to avoid falling into the local optimum, two subgroups communicate information in the evolutionary process. The experimental results show, compared to the other clustering methods for missing data, PSOABC-FC has the higher accuracy of classification, at the same times, it has more average accuracy rate for clustering and the less average intra-class distance.

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information.
