rsmix's Issues

Reproduce Confusion

Hey, sorry to bother you. I rerun the code as your instruction in the README. For DGCNN on ModelNet40, the accuracy of RSMix is rather lower than the base version.
From
python main.py --exp_name=rsmix_dgcnn_1024 --model=dgcnn --num_points=1024 --k=20 --use_sgd=True --beta 1.0 --epochs 500
to
python main.py --exp_name=rsmix_dgcnn_1024 --model=dgcnn --num_points=1024 --k=20 --use_sgd=True --beta 0. --rsmix_prob 0. --epochs 500
Is there anything wrong? Thank for your reply.

Benchmarking results of RSMix on Common Corruptions

Dear Authors,

Thank you so much for this nice repo. We recently proposed a new corruption robustness benchmark called ModelNet40-C and test RSMix on several corruptions from our dataset. We find that RSMix is robust to "density" corruptions.
Github repo: https://github.com/jiachens/ModelNet40-C
Paper link: https://arxiv.org/abs/2201.12296

I wonder if you can mention our benchmark and dataset in your repo to highlight the results. Thank you!

What is The Meaning of "Raw" in The Table?

Hi,

Thanks for the great work! I have some inquires:

1. As written in the title, what is the meaning of "Raw" in the Table 3 in the paper? Is it equal to "pre-aligned", "Unaligned", or something other? Could you confirm which dataset is specified as "Raw" in that table? Is it no (1), (2) or (3)? The downloaded link are provided in the numbers, and I also put screenshot for each number below.
2. Or could you please provide the dataset links used in Table 3: (a) Pre-Aligned, (b) Unaligned and (c) Raw?

Many thanks :)

How do You Visualize the Point Cloud?

Hi!

Thanks for the great work. I wonder, how do you visualize the point cloud sample in the paper? It looks great and natural/ Do you use certain software? Thanks.

Can you open source the supplementary material of your paper ?

Question about Equation 7 and Figure 4

If all points are selected as in equation 7, why there are part point selected in figure 4?
