Title: Optimization of modular granular neural networks using bio-inspired optimization algorithms with fuzzy parameter adaptation for human recognition

Melin, Patricia Spearker: Patricia Melin, Tijuana Institute of Technology, Tijuana, Mexico

Abstract: In this talk, new models of modular neural networks optimized with bio-inspired optimization algorithms using fuzzy parameter adaptation are proposed. The models use a granular approach based on analyzing database complexity. In this case the proposed method is tested with the problem of human recognition based on face information. The ORL and the ESSEX face databases are used to test the effectiveness of the proposed method. To compare with other related works using the same databases, four cases are established (3 for the ESSEX Database and 1 for the ORL Database). The results using the proposed method are better than the results achieved by other works, and this affirmation is based on a statistical comparison of results. The main idea is to design the architectures of modular neural networks using bio-inspired optimization methods, such as particle swarm optimization, grey wolf optimization and the firefly algorithm. The distribution of persons in each granule is determined by an initial analysis, resulting in a grouping of data with the same complexity. The proposed method allows the optimization of multiple modular neural networks that use different sizes of data sets for the training phase, which means that multiple results can be obtained.
