What is weak augmentation for teacher network?

[Yontara]

Thank you for your great research about ssl for 3D detection.

As the title states, I have some questions about weak augmentation for teacher network.

My questions are what augmentations are adopted, and why do they need.

I wonder why weak augmentations are applied because I think the teacher network will be able to generate better pseudo labels if augmentation is not applied.

I know that time has passed since the publication of your paper, but I would like you to answer my question. Thank you.
