摘要
通过分析现有主成分分析算法的不足,研究了如何利用小波包算法实现快速近似主成分分析算法的问题,并对两种算法的复杂度进行了比较。实验结果表明:提出的快速近似主成分分析算法在精度和速度两个方面都具有明显的优势。
The disadvantage of Principal component analysis algorithm is presented and a fast approximate Principal component analysis algorithm is studied on the basis of wavelet packet algorithm. The complexity of these two kinds of algorithms are compared. The experiment shows that the algorithm proposed above has obvious advantages in precision and speed.
