Special Issue on "Hybrid Intelligent Systems"Oscar Castillo, Patricia MelinGuest Editors:

Special Issue on Hybrid Intelligent Systems

This Special Issue contains a selection of papers from the IFSA 2007 World Congress that were extendedand significantly improved over the conference proceeding's version of the papers. There are seven papers inthis Special Issue, containing a range of topics of the Hybrid Intelligent Systems area. In particular, thereare papers on fuzzy logic, neural networks, genetic algorithms, ant colony optimization, and combinationsof these techniques.

The first paper, by Miguel Porta ., describes an Ant Colony Optimization (ACO) Path Planner Usinga FIS for Path Selection Adjusted with a Simple Tuning Algorithm, which proposes an evolutionary approachfor designing paths for autonomous mobile robots that also uses fuzzy logic. Simulation and experimentalresults with an autonomous robot shows the feasibility of the proposed hybrid approach combining ACO andfuzzy logic.

The second paper, by Ricardo Martinez , describes an Intelligent Control for a Perturbed Autono-mous Wheeled Mobile Robot Using Type-2 Fuzzy Logic and Genetic Algorithms, which proposes the use ofinterval type-2 fuzzy logic for designing stable intelligent controllers of a mobile robot. Genetic algorithmsare also used to automatically obtain the optimal parameters of the interval type-2 fuzzy logic controllers.Simulation results show the effectiveness of the proposed hybrid intelligent approach.

The third paper, by Gerardo Mendez and Angeles Hernandez, describes Hybrid Learning of Interval Type-2 Fuzzy Systems Based on Orthogonal Least Squares and Back Propagation for Manufacturing Applications,which proposes a hybrid method for learning the parameters of an interval type-2 fuzzy system and itsapplication for intelligent manufacturing. The hybrid learning method combines orthogonal least squaresand backpropagation for achieving better performance. Simulation results illustrate the usefulness of thehybrid learning algorithm.

The fourth paper, by Kadda Zemalache , describes the Control of a Drone: Study and Analysis of theRobustness, which proposes a method for analysis and design of a stable and robust controller for a drone.Simulation and experimental results show the feasibility of the proposed approach for control.

The fifth paper, by Fevrier Valdez and Patricia Melin, describes a Comparative Study of Particle SwarmOptimization and Genetic Algorithms for Complex Mathematical functions, which proposes a combination oftwo evolutionary methods for achieving optimization of complex mathematical functions. The use of particleswarm optimization and genetic algorithms for complex function optimization is analyzed, and the optimi-zation of neural networks is proposed.

The sixth paper, by Miguel Lopez and Patricia Melin, describes Response Integration in Ensemble NeuralNetworks using the Sugeno Integral and Fuzzy Inference System for Pattern Recognition, which proposesusing fuzzy logic models to integrate the results of the modules in an ensemble architecture. The use of theSugeno integral and fuzzy inference systems is tested for fingerprint recognition. Simulation results areencouraging and other recognition problems can be solved with the same approach.

The seventh paper, by Denisse Hidalgo and Oscar Castillo, describes Type-1 and Type-2 Fuzzy InferenceSystems as Integration Methods in Modular Neural Networks for Multimodal Biometry and its Optimizationwith Genetic Algorithms. The paper proposes the use of fuzzy systems for integrating results of modularneural networks, and genetic algorithms for finding the optimal parameters of the fuzzy systems. Simulationresults in the recognition of persons illustrate the potential of the proposed approach.
