Reviews: Point-Voxel CNN for Efficient 3D Deep Learning

This work proposes an efficient method for processing 3D data in deep neural networks. The method is evaluated on competitive benchmarks and shows consistent improvements in efficiency while retaining or even improving predictive accuracy. The authors promise to make the code available. Three expert reviewers initially assessed the work as 7/8/6, with minor concerns. The authors provided a detailed rebuttal that was read and discussed by all reviewers.
