Parameter is Not All You Need: Starting from Non-Parametric Networks for 3D Point Cloud Analysis
Renrui Zhang, Liuhui Wang, Ziyu Guo +4
We present a Non-parametric Network for 3D point cloud analysis, Point-NN, which consists of purely non-learnable components: farthest point sampling (FPS), k-nearest neighbors (k-…

Nearest Neighbors Meet Deep Neural Networks for Point Cloud Analysis
Renrui Zhang, Liuhui Wang, Ziyu Guo +1
Performances on standard 3D point cloud benchmarks have plateaued, resulting in oversized models and complex network design to make a fractional improvement. We present an alternat…
