多元数据分析的主分量分析投影，通过反复训练模板能有较高的识别率，是本科毕设的题目，主要是基于mtlab的程序，FIR 底通和带通滤波器和IIR 底通和带通滤波器，仿真效果非常好，迭代自组织数据分析。- Principal component analysis of multivariate data analysis projection, Through repeated training XszPlTOlate have higher recognition rate, The title of the commercial is undergraduate course you Mainly based on the mtlab procedures, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter, Simulation of the effect is very good, Iterative self-organizing data analysis.
