Model Question

[marshzero]

Hi, thanks for your wonderful work.
And I have some questions about models in /networks/cls/pct.py.

1. Does Point_Transformer on 86 line corresponds to a model without neighbor embedding?
2. Does Point_Transformer2 on 34 line correspond to the final model of the paper?
3. pos_xyz corresponds to positional embedding? and why we ues it?

Maybe I have a wrong understanding and you can give me some advice? Thanks!

Thanks for your attention.
For your question :
1.2 Yes
3. Pos_xyz corresponds to positional embedding, i find it can avoid overfitting in classification task.
