An hybrid training method for B-spline neural networks, Trabalho apresentado em IEEE International Workshop on Intelligent Signal Processing, 2005. In Proceedings of the IEEE International Workshop on Intelligent Signal Processing, 2005. University of Algarve Portugal, 2005.0-7803-9030-XAUT: ARU00698; CCA01443;http://hdl.handle.net/10400.1/2235Current and past research has brought up new views related to the optimization of neural networks. For a fixed structure, second order methods are seen as the most promising. From previous works we have shown how second order methods are of easy applicability to a neural network. Namely, we have proved how the Levenberg-Marquard possesses not only better convergence but how it can assure the convergence to a local minima. However, as any gradient-based method, the results obtained depend on the startup point. In this work, a reformulated Evolutionary algorithm - the Bacterial Programming for Levenberg-Marquardt is proposed, as an heuristic which can be used to determine the most suitable starting points, therefore achieving, in most cases, the global optimum.engLevenberg-Marquard algorithmB-SplinesGenetic ProgrammingBacterial AlgorithmLocal and global minimaconference object2013-01-26
