Table 1 Four variants of PCA based on SVD
From: Remote sensing of burned areas via PCA, Part 1; centering, scaling and EVD vs SVD
Transformations prior decomposition | Non-scaling | Scaling |
|---|---|---|
Non-centering | uncentered, unscaled (A) | uncentered, scaled (B) |
Centering | centered, unscaled (C) | centered, scaled (D) |
