说明: 近红外光谱分析中要从复杂的信息中有效地提取相关信息建立可靠的模型,选择的训练集要具有较好的代表性。目前.样本的选择方法主要包括random sampling(RS),Kennard—Stone(KS).sample set partitioning based on joint x-y distance(SPXY)等方法 。(selecting a representative subset in NIR data using SPXY, the random sampling,and Kennard—Stone methods )

Kalman
对于一个含有明显噪声的心电信号进行卡尔曼滤波处理,最大程度地 “还原”信号,达到去除噪声的目的。卡尔曼滤波(看成维纳滤波的一种实现方法)的特点如下:
a) 是根据上一状态的估计值X(n-1)和当前状态的观测值Z(n)推出当前状态的估计值X(n)的滤波方法,不需要用过去的全部观测值。
b) 它是用状态方程和递推方法进行估计的,因而卡尔曼滤波对信号的平稳性和时不变性不做要求。
c) 使用全部观测值保证平稳性。(Kalman in matlab,if you need it,please download it.)
