BP神经网络主成分分析在试飞数据预测中的应用

本文采用主成分分析与BP神经网络相结合的方法对试飞数据进行了预测，同时还对BP神经网络主成分分析法与全要素BP神经网络分析法进行了比较．结果表明BP神经网络主成分分析法具有精度更高、收敛速度更快等特点。

The Forecast of the Pre-Processing Data with BP Neural Network and Principal Component Analysis

This passage talks about how to forecast the pre-processing data with the BP Neural Network and the Principal Component Analysis, and compares the BP Neural Network--Principal Component Analysis method with the whole factor---BP Neural Network. The result indicates that the BP Neural Network--Principal Component Analysis method has the characteristics of higher precision and faster convergence speed etc.
