cskmeans
cskmeans 聚类算法的一种
1. 分裂法(partitioning methods):给定一个有N个元组或者纪录的数据集,分裂法将构造K个分组,每一个分组就代表一个聚类,K<N。而且这K个分组满足下列条件:(1) 每一个分组至少包含一个数据纪录;(2)每一个数据纪录属于且仅属于一个分组(注意:这个要求在某些模糊聚类算法中可以放宽);对于给定的K,算法首先给出一个初始的分组方法,以后通过反复迭代的方法改变分组,使得每一次改进之后的分组方案都较前一次好,而所谓好的标准就是:同一分组中的记录越近越好,而不同分组中的纪录越远越好。使用这个基本思想的算法有:K-MEANS算法、K-MEDOIDS算法、CLARANS算法;()

LMSfilter
假设一个接收到的信号为:x(t)=s(t)+n(t), 其中s(t)=A*cos(wt+a), 已知信号的频率w=1KHz,
而信号的幅度和相位未知,n(t)是一个服从N(0,1)分布的白噪声。为了利用计算机对信号进行处理,
将信号按10KHz的频率进行采样。
通过对x(t)进行LMS自适应信号处理,从接收信号中滤出有用信号s(t).
在未知信号频率的情况下,通过对x(t)进行LMS自适应信号处理,从接收信号中滤出有用信号s(t).
(Assuming a received signal: x (t) = s (t)+ n (t), one of s (t) = A* cos (wt+ a), the known frequency signal w = 1KHz,
And the signal amplitude and phase of the unknown, n (t) is a subject to N (0,1) the distribution of white noise. The use of computers in order to deal with the signal,
The signal by sampling frequency of 10KHz.
Of x (t) for LMS adaptive signal processing, filtering from the received signal in the useful signal s (t).
Frequency signals in unknown circumstances, the adoption of x (t) for LMS adaptive signal processing, filtering from the received signal in the useful signal s (t).)
