EDAS: Efficient and Differentiable Architecture Search

no code implementations3 Dec 2019 Hyeong Gwon Hong, Pyunghwan Ahn, Junmo Kim

Transferrable neural architecture search can be viewed as a binary optimization problem where a single optimal path should be selected among candidate paths in each edge within the repeated cell block of the directed a cyclic graph form.

PBP-Net: Point Projection and Back-Projection Network for 3D Point Cloud Segmentation

no code implementations2 Nov 2020 JuYoung Yang, Chanho Lee, Pyunghwan Ahn, Haeil Lee, Eojindl Yi, Junmo Kim

In this paper, we propose a simple and efficient architecture named point projection and back-projection network (PBP-Net), which leverages 2D CNNs for the 3D point cloud segmentation.
