摘要
针对复杂神经网络模型的结构特性和BP网络梯度下降法的缺点,将遗传算法与神经网络相结合,提出了基于改进连续化遗传算法的神经网络学习方法,并将其应用于大型乙烯裂解过程产品分布预测。
According to the structure characteristics of neural networks, this paper proposes a neural networks learning algorithm based on continuous genetic algorithm. By making use of continuous genetic operators, the algorithm can directly probe the solution in state space avoiding the process of coding and decoding, and can improve the searching performance. A numerical example of predicting the products distribution of gas oil pyrolysis shows that the improved algorithm is effective.
