I just want to have a simple PCA to reduce my dimensionality of let say 400 * 5000 to 400 * 4
meaning reduce from 5000 to 4.
I am not sure where can I set the value of reduction.
I am trying to follow:
Then:
The dataset of ingredient is 13 * 4
Output:
coeff = 4×4
-0.0678 -0.6460 0.5673 0.5062
-0.6785 -0.0200 -0.5440 0.4933
0.0290 0.7553 0.4036 0.5156
0.7309 -0.1085 -0.4684 0.4844
I am wondering can i change it to output of 13 *2 (13 x 2)
