SnowflakeNet: Point Cloud Completion by Snowflake Point Deconvolution with Skip-Transformer

2 code implementations ICCV 2021

However, previous methods usually suffered from discrete nature of point cloud and unstructured prediction of points in local regions, which makes it hard to reveal fine local geometric details on the complete shape.

Snowflake Point Deconvolution for Point Cloud Completion and Generation with Skip-Transformer

1 code implementation18 Feb 2022

Our insight into the detailed geometry is to introduce a skip-transformer in the SPD to learn the point splitting patterns that can best fit the local regions.

Snowflake: Scaling GNNs to High-Dimensional Continuous Control via Parameter Freezing

1 code implementation NeurIPS 2021

Recent research has shown that graph neural networks (GNNs) can learn policies for locomotion control that are as effective as a typical multi-layer perceptron (MLP), with superior transfer and multi-task performance (Wang et al., 2018; Huang et al., 2020).

Score-Based Point Cloud Denoising

2 code implementations ICCV 2021

Since $p * n$ is unknown at test-time, and we only need the score (i. e., the gradient of the log-probability function) to perform gradient ascent, we propose a neural network architecture to estimate the score of $p * n$ given only noisy point clouds as input.
