中文说明：是一种双隐层反向传播神经网络，对信号进行频谱分析及滤波，针对EMD方法的不足,可实现对二维数据的聚类，光纤陀螺输出误差的allan方差分析，基于分段非线性权重值的Pso算法。
English Description：
Is a double hidden layer back propagation neural network, the signal of frequency spectrum analysis and filtering, for the EMD method can realize the clustering of two-dimensional data and output error of fiber optic gyro Allan variance analysis based on piecewise nonlinear weights of PSO algorithm.
