Sherpa3D: Boosting High-Fidelity Text-to-3D Generation via Coarse 3D Prior

1 code implementation CVPR 2024 Fangfu Liu, Diankun Wu, Yi Wei, Yongming Rao, Yueqi Duan

Instead of retraining a costly viewpoint-aware model, we study how to fully exploit easily accessible coarse 3D knowledge to enhance the prompts and guide 2D lifting optimization for refinement.

Discovering Dynamic Causal Space for DAG Structure Learning

1 code implementation5 Jun 2023 Fangfu Liu, Wenchang Ma, An Zhang, Xiang Wang, Yueqi Duan, Tat-Seng Chua

Discovering causal structure from purely observational data (i. e., causal discovery), aiming to identify causal relationships among variables, is a fundamental task in machine learning.

Boosting Differentiable Causal Discovery via Adaptive Sample Reweighting

1 code implementation6 Mar 2023 An Zhang, Fangfu Liu, Wenchang Ma, Zhibo Cai, Xiang Wang, Tat-Seng Chua

Despite great success in low-dimensional linear systems, it has been observed that these approaches overly exploit easier-to-fit samples, thus inevitably learning spurious edges.
