چکیده

A novel cooperative evolutionary system, i.e., CGPNN, for automatic design artificial neural networks (ANN’s) is presented where ANN’s structure and parameters are tuned simultaneously. The algorithms used in CGPNN combine genetic algorithm (GA) and particle swarm optimization (PSO) on the basis of a direct encoding scheme. In CGPNN, standard (real-coded) PSO is employed to training ANN’s free parameters (weights and bias) and binarycoded GA is used to find optimal ANN’s structure. In the simulation part, CGPNN is applied to the predication of tool life. The experimental results show that CGPNN has good accuracy and generalization ability in comparison with other algorithms.

Evolving a Cooperative Population of Neural Networks by Minimizing Mutual Information

Evolutionary ensembles with negative correlation learning (EENCL) is an evolutionary learning system for learning and designing neural network ensembles [1]. The fitness sharing used in EENCL was based on the idea of “covering” the same training patterns by shared individuals. This paper explores connection between fitness sharing and information concept, and introduces mutual information into ...
