Abstract To overcome existing problems of BP neural network,we introduce the cascade-correlation algorithm into the neural network construction.The proposed algorithm has a faster convergence than BP algorithm,and it can decide its own network architecture based on problems to be solved.That means it can expand network topology to learn new samples.The initial network of the standard cascade-correlation algorithm has only an input layer and an output layer,while the improved algorithm starts with an appropriate BP network architecture (including hidden layers).In addition,in order to prevent weight-ill growth,a regularization term is added to objective functions in candidate hidden units training to decay weights.Simulation experiments demonstrate that the improved cascade-correlation algorithm has faster convergence and stronger generalization ability.Cross-plots of five attributes such as instantaneous-intensity ratio,amplitude,frequency,curve-length ratio,and adjacent-trace correlation,show that first breaks peaked by the proposed algorithm can be easily and reliably discriminated.The proposed algorithm achieves good performance in the first break picking on real data.
