I created a classifier by trained SVM and PCA as well as normalization transformation. And use Request/Response Excel to test.enter image description here And if I only input for one row, all the PCA would be "0" enter image description here but if I put more than one row together then the result would change and both behavior doesn't make sense. enter image description here I read some other questions below and I wonder if something wrong in "Normalization" calculating that it didn't count by referring "Applying transformation" but simply normalizing by data input.
