An Optimization Algorthm for Artificial Neural Networks Based on Active Evolution

The paper proposes an automatic optimization algorithm for neural networks based on active evolution and genetic algorithms. It is used to solve the network's parameters such as the weight and structural value. In order to solve the problem of low performance of genetic algorithms, the active evolution method is applied to the neural networks. The simulation result shows that the method has a higher convergence speed, improves the network's structural values and weight, and improves network's forecasting accuracy.
