Self-Supervised Learning for Domain Adaptation on Point-Clouds
I couldn't get the visualizations I wanted after the reconstruction.The network doesn't seem to be converging.Could you please send me the weight parameters after pre-training
Hi, thank you for your work.
I am getting this error
Traceback (most recent call last):
File "PointDA/trainer.py", line 12, in
import utils.log
ModuleNotFoundError: No module named 'utils'
when using this command:
python PointDA/trainer.py
I noticed the reported accuracy of pointdan is different from the original paper.
http://papers.nips.cc/paper/8940-pointdan-a-multi-scale-3d-domain-adaption-network-for-point-cloud-representation.pdf
Is it due to aligning the upward direction of 3 datasets, or there are other reasons?
How can I reproduce the experiment on pointdan?
Thanks for replying!
I noticed that the experiment results of "DefRec+PCM" is not consistent among Table1-4, especially Table 4 looks better, Is it due to the experimental settings are different, or other reasons?
Dear Idan,
I couldn't find the other types of region selection methods in defrec.py
Can you tell me where I can find it?
Hi,
When i dont install the repo, i will meet problems in #7. But it works when i install the repo.
However, i check the setup.py, it doesn't add utils into environment, thats confused to me.
Would you please help me understand it?
Hi, thanks for sharing this great work. Could you kindly share the implementation of 'Reconstructing Space' in your paper? I didn't find the offical codes for this paper.
Thank you so much!
Hi! from the network implementation (PointSegDA experiments) I see that you pruned many BatchNorm layers which were in the original pytorch dgcnn implementation, for example in the main feature extractor 'shared_layers'. Is there any specific reason to do so? Have you found that removing BN layers the results are more stable across domains?
Thanks a lot
Thanks for your code. It is a really interesting work.
I found your implementation of DGCNN is different from the official implementation. It seems that you use the top branch of the segmentation network of DGCNN instead of the classification work.
The classification work may not contain the transform net and the embedding feature is the concatenation of the max pooling and average pooling features.
Is that right?
Dear Idan,
I use the default parameters to run the code about PointSegDA task. The results are greatly different from those on the paper. Such as the results of FAUST to MIT mIOU: 0.6211 , in paper is 79.7 ± 0.3,MIT to FAUST our mIOU: 0.4400, in paper is 67.1 ± 1.0 . The results are very different, could you please help me to explain what causes it.
Could you show the paraments with the DefRec_weight, noisy_std, and so on.
What is the difference of Table 1 and 2 in your paper? The results seem different but I cannot find the different experimental settings or descriptions. Thanks.
I tried to apply this method to outdoor point cloud scenes, and found that this method occupied too much memory and miou did not improve much. Is this method not suitable for large-scale outdoor scenes?
Hi,
Nice work and thanks for sharing the code!
I have one question regarding the baseline results from ModelNet to ShapeNet. It seems that the baseline already achieved 83.3%. However in PointDA, the baseline is 42.5%. Also I noticed that the data for training are different -- the alignment has been done in your dataset. Would that be the reason for the significant improvement for that baseline?
Thanks!
Hi, thanks for sharing this great work. Could you kindly share the implementation of 'T-SNE' in your paper?
