Multilayer Perceptron: Architecture Optimization and Training

The multilayer perceptron has a large wide of classification and regression applications in many fields: pattern recognition, voice and classification problems. But the architecture choice has a great impact on the convergence of these networks. In the present paper we introduce a new approach to optimize the network architecture, for solving the obtained model we use the genetic algorithm and we train the network with a back-propagation algorithm. The numerical results assess the effectiveness of the theoretical results shown in this paper, and the advantages of the new modeling compared to the previous model in the literature

Finite Element Method for the Electrical Scalar Helmholtz Field Modeling, in Application to 2.4 GHz Waveguide Cylindrical Antenna

Electrical scalar Helmholtz equation is necessary to understand the field behavior. The cylindrical antennas presenting cavities like waveguides are a major problem related to field prediction. We used finite element method to solve the Helmholtz equation governing the system. We imposed two kind of boundary conditions, first, Dirichlet boundary condition, and second, absorbing boundary condition. An adaptive shape mesh generation is also used. Finally numerical results are given. The polar plot of our cylindrical antenna has directional pattern. This antenna is directive.
