摘要
介绍前向人工神经网络模型，并与传统的统计学线性模型进行比较。为了适应时间序列变量的特点，对逆传播模型进行了改进，并对太阳黑子活动的观察值这一典型的时间序列进行了分析，并检验了模型的预测能力。
The author introduces the forward manual nerve net model and makes a comparison with the linear model of traditional statistics. The counter propagation model is improved in order to fit in with the characteristic of time sequence variable. And the author analyses the typical time sequence of the observed value of sunspot moving , examines the forecasting ability of the model and gets good results.
