Details on pretrained models for downstream tasks (K400).

[LSanghyeok]

Hi! It's an intriguing work!
I have a question about K400 pre-trained models.
Did you use ImageNet-1K pre-trained models to pre-train K400 datasets for downstream tasks (e.g., Breakfast, COIN, etc) or simply train K400 from scratch without image-pretrained models?

Thanks.

HI! As claimed in the caption, we use ImageNet pretrained models for K400 by default. For the models marked with †, we trained it from scratch with masked modeling.
