Masked BRep Autoencoder via Hierarchical Graph Transformer
Yifei Li, Kang Wu, Wenming Wu +1
We introduce a novel self-supervised learning framework that automatically learns representations from input computer-aided design (CAD) models for downstream tasks, including part…
Neural Modular Physics for Elastic Simulation
Yifei Li, Haixu Wu, Zeyi Xu +2
Learning-based methods have made significant progress in physics simulation, typically approximating dynamics with a monolithic end-to-end optimized neural network. Although these…
Universal Lesion Segmentation Challenge 2023: A Comparative Research of Different Algorithms
Kaiwen Shi, Yifei Li, Binh Ho +2
In recent years, machine learning algorithms have achieved much success in segmenting lesions across various tissues. There is, however, not one satisfying model that works well on…
Learning Physical Simulation with Message Passing Transformer
Zeyi Xu, Yifei Li
Machine learning methods for physical simulation have achieved significant success in recent years. We propose a new universal architecture based on Graph Neural Network, the Messa…
