HHT
目前,互联网上HHT信号处理技术有
三种实现方式,采用MATLAB编程语言,一种是法国研究者设计的G Rilling 2007
另一种是MATLAB文件交换中心由Alan Tan开发的plot_hht程序包,第三种是台湾中央大学数据研究中心提供的EEMD包。
其中,我使用了plot_hht程序包,其使用了三个终止条件,驻留分量的单调性,极值点与零点的个数相差不超过1,还有黄锷1998经典文献提出的
SD>0.1,单调性的判断,并不是去判定驻留分量是否是单调函数,而是当曲线是双曲线时,循环结束,由于没有考虑端点效应,程序比较简洁,好读懂,大家
学习HHT可以从这个程序包入手,在此抛砖引玉,希冀有人能比较这三种不同的算法的性能和时间复杂度,以及对各种信号的适应性。
(There provides three types of HTT program packages: one developed by France researcher G. Rilling 2007, the other provided by by Alan Tan from Matlab file exchange center and the third one by Taiwan Central University Data Research Center. Please start from the simple one by Tan to learn more.)

说明: 遗传算法改进的模糊C-均值聚类MATLAB源码.模糊C-均值算法容易收敛于局部极小点,为了克服该缺点,将遗传算法应用于模糊C-均值算法(FCM)的优化计算中,由遗传算法得到初始聚类中心,再使用标准的模糊C-均值聚类算法得到最优分类结果。(Improved genetic algorithm Fuzzy C-Means Clustering MATLAB source. Fuzzy C-means algorithm converges to local minimum easily, in order to overcome the shortcomings, the genetic algorithm used fuzzy C-means algorithm (FCM) in the optimization calculation, the The initial cluster centers of genetic algorithm, then using the standard fuzzy C-means clustering algorithm to obtain the optimal classification results.)
