Parallel Classification System based on an Ensemble of Mixture of Experts

The classification of large amounts of data is a challenging problem that only a small number of classification algorithms can handle. In this paper we propose a Parallel Classification System based on an Ensemble of Mixture of Experts (PCEM). The system uses MIMD (Multiple Instruction and Multiple Data Stream) architecture, using a set of process that communicates via messages. PCEM is implemented using parallel schemes of traditional classifiers, for the mixture of experts, and using a parallel version of a Genetic Algorithm to implement a voting weighted criterion. The PCEM is a novel algorithm since it allows us to classify large amounts of data with low execution times and high performance measures, which makes it an excellent tool for in classification of large amounts of data. A series of tests were performed with well known databases that allowed us to measure how PCEM performs with many datasets and how well it does compared with other systems available.
