알고리즘 썸네일형 리스트형 PCA를 돌리는 실제 C코드 Algorithm and Performance PCA is implemented as a eigen value - eigen vector problem. Dealing with large number of data, usually it contatins neally normal distributed values. For that case, PCA eigen value - eigen vector program reduces its calculation amount along its running steps continually. In general, PCA algorithm needs n^3 order caculations and n order memory. However, for most cases n^.. 이전 1 다음
