Weakness： 1. This paper is built on the SPAIR framework and focuses on point cloud data, which is somehow incremental. 2. There is no ablation study to validate the effectiveness of the proposed components and the loss. 3. It is hard to follow Sec. 3.2. The author may improve it and give more illustrations and examples. 4. It is unclear how the method can work and decompose a scene into different objects. I did not see how Chamfer Mixture loss can achieve this goal. More explanation should go here.
