地质数据的BP网络分析方法

数学地质中母函数选取和系数求解是函数逼近的两个关键问题，目前在地质数据的多元统计分析中广泛应用的回归分析或其他映射方法均有局限性。本文采用ＡＮＮ中的ＢＰ网络模型较好地解决了这两个问题，并对理论和实际和数据进行了比较与验证，结果表明，ＢＰ网络有助于提高地质数据处理的可靠性与预测的精度。

Back Propagation Neutral Network and Its Application in Processing Geological Data

he fundamental function selection and coefeicient solution are important for function approximation method. The generalregress analysis or other cast methods have some disadvantages,The back propagation neutral network(BP)can give a good solu-tion. Comparison of theoretical calculation with the test data shows that BP neutral network can improve the rewability of dataprocessing and the accuracy of prediction.
