AugMix in PyTorch (8)

Buy Me a Coffee

*Memos:

• My post explains AugMix() about no arguments and full argument.
• My post explains AugMix() about severity argument (1).
• My post explains AugMix() about severity argument (2).
• My post explains AugMix() about severity argument (3).
• My post explains AugMix() about mixture_width argument (1).
• My post explains AugMix() about mixture_width argument (2).
• My post explains AugMix() about mixture_width argument (3).
• My post explains AugMix() about chain_depth argument (2).
• My post explains AugMix() about chain_depth argument (3).

AugMix() can randomly do AugMix to an image as shown below. *It’s about chain_depth argument (1):
