Add Skip connection in the segmentation task

[Chen-yuiyui]

Hi!Thank you for the great work. Now I want to use your net for the Semantic Segmentation task, so I want to modify the Part Segmentation model. It seems like your model architecture only replaced the PointNet's backbone. Can I add skip connection after the set abstraction operation(like pointnet++)? Have you tried the Semantic Segmentation?

Hi, thanks for your interest. Sure, you can do that. We didn't try this but it should work.
