代码说明:

用于matlab模式识别(分类和回归)的特征变量提取方法,竞争性自适应重加权算法(CARS)是通过自适应重加权采样(ARS)技术选择出PLS模型中回归系数绝对值大的波长点,去掉权重小的波长点,利用交互验证选出RMSECV指最低的子集,可有效寻出最优变量组合。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理,希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)
