Hi,

I found mlp and mlp2 in the modules like pointnet_sa_module, set_upconv_module. Sometime mlp is [] while in other cases mlp2 is []. Is there any rule or do you have any suggestions about when to use them or not?

mlp2 is the MLP layers used after max pooling. Whether and how to use them are simply architectural design choices.
