汇报提要: In this talk, we propose a model called CP3, which is a Channel Pruning Plug-in for Point-based network. CP3 is elaborately designed to leverage the characteristics of point clouds and PNNs in order to enable 2D channel pruning methods for PNNs. Specifically, it presents a coordinate-enhanced channel importance metric to reflect the correlation between dimensional information and individual channel features, and it recycles the discarded points in PNN’s sampling process and reconsiders their potentially-exclusive information to enhance the robustness of channel pruning. Experiments on various PNN architectures show that CP3 constantly improves state-of-the-art 2D CNN pruning approaches on different point cloud tasks.
