Compute how much your training set grows after augmentation, from the number of transforms and the repeat factor.
实际去重后可能低于估算。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Volume | total = originals x augmentations per sample | Data augmentation practice |
| Online and offline | online augmentation adds more variety than fixed offline copies | Data augmentation practice |
| Cost | raising the multiplier lengthens epochs linearly | Deep learning practice |
