ReliCAD: From Uncertain LLM Generation to Reliable Parametric CAD Modeling
Peng Zheng, Xintong Dong, Chuanyang Li +5
Large language models have shown considerable potential for natural-language-driven parametric CAD modeling. However, a fundamental contradiction exists between their probabilistic…
HistCAD: Constraint-Aware Parametric CAD Histories for Evaluating Editability
Xintong Dong, Chuanyang Li, Peng Zheng +5
Sketch constraints specify geometric conditions for constructing and modifying parametric CAD models. We study whether predicted constraints allow a given history to reproduce the…
Cross-Hierarchical Bidirectional Consistency Learning for Fine-Grained Visual Classification
Pengxiang Gao, Yihao Liang, Yanzhi Song +1
Fine-Grained Visual Classification (FGVC) aims to categorize closely related subclasses, a task complicated by minimal inter-class differences and significant intra-class variance.…
A Multigrid Graph U-Net Framework for Simulating Multiphase Flow in Heterogeneous Porous Media
Jiamin Jiang, Jingrun Chen, Zhouwang Yang
Numerical simulation of multi-phase fluid dynamics in porous media is critical to a variety of geoscience applications. Data-driven surrogate models using Convolutional Neural Netw…
BrickPal: Augmented Reality-based Assembly Instructions for Brick Models
Yao Shi, Xiaofeng Zhang, Ran zhang +4
The assembly instruction is a mandatory component of Lego-like brick sets.The conventional production of assembly instructions requires a considerable amount of manual fine-tuning,…
