是机器学习的例程，结合PCA的尺度不变特征变换(SIFT)算法，有小波分析的盲信号处理，这个有中文注释，看得明白，采用热核构造权重，可以广泛的应用于数据预测及数据分析,基于互功率谱的时延估计。- Machine learning routines, Combined with PCA scale invariant feature transform (SIFT) algorithm, There Wavelet Analysis Blind Signal Processing, The Chinese have a comment, understand it, Thermonuclear using weighting factors Can be widely used in data analysis and forecast data, Based on the time delay estimation of power spectrum.
