GEOMETRIC AFFINE MODULE #51

Closed AArutoria closed 2 years ago

AArutoria commented 2 years ago

May I ask what part of the GEOMETRIC AFFINE MODULE code is? Looking forward to the author's answer

@AArutoria Hi, I remember that I responsed to you. The code is here: https://github.com/ma-xu/pointMLP-pytorch/blob/b5dcf4d0ca2085d10fe1dc5e6f2972cddec8399d/classification_ModelNet40/models/pointmlp.py#L171 Please let me know if any further questions.

Please let me know if any further questions.

Thanks to the author for answering questions. I have a few more questions. The first point: Figure 2 shows a stage of PointMLP, which shows that the point cloud is directly input into the GEOMETRIC AFFINE MODULE. But in Figure 6, the point cloud enters stage1 after the Embedding operation. Does this mean that both point clouds and embedded point clouds can be input into GEOMETRIC AFFINE MODULE? Second point: In Figure 6, I can't see where the GEOMETRIC AFFINE MODULE is. Is it in Embedding or in stage1? Thanks again for the author's answer

@AArutoria

  1. yes. BTW, the inputs in figure 2 actually are features. we plot as points for better visualization. You can refer the codes for better understnading.
  2. It is in the aggregation. Please correct me if I remember wrong.

Feel free to ask me if you have any further questions.

Thanks for your patient answer. I have a new understanding of your code
