摘要
利用一种改进粒子群优化算法的粒子速度、位置修正公式替代传统BP算法的梯度下降法;并基于改进BP神经网络建立了电磁兼容问题中导线串扰电压的预测模型;实验结果表明改进后的方法在预测精度和小样本性能方面要比传统BP神经网络高得多.
In this paper,particle velocity and position correction formula in improved particle swarm optimization was usedinstead of gradient descent in traditional BP algorithm;and prediction model of crosstalk voltage in EMC was established based onimproved BP neural network;Experimental results showed that forecasting accuracy and small sample performance of improvedmethod was much higher than the traditional BP neural network.
