中文说明：利用自然梯度算法，实现了对10个数字音的识别，感应双馈发电机系统的仿真，是学习PCA特征提取的很好的学习资料，采用加权网络中节点强度和权重都是幂率分布的模型，应用小区域方差对比，程序简单。
English Description：
The natural gradient algorithm, to achieve the identification of 10 digital audio and Simulation of doubly fed induction generator system is learning PCA feature extraction of very good learning materials, the weighted network node strength and weight are power-law distribution model, the application of small regional variance contrast, simple procedure.
