DualReg: Dual-Space Filtering and Reinforcement for Rigid Registration
Jiayi Li, Yuxin Yao, Qiuhang Lu +1
Noisy, partially overlapping data and the need for real-time processing pose major challenges for rigid registration. Considering that feature-based matching can handle large trans…
DRIFT-Net: A Spectral--Coupled Neural Operator for PDEs Learning
Jiayi Li, Flora D. Salim
Learning PDE dynamics with neural solvers can significantly improve wall-clock efficiency and accuracy compared with classical numerical solvers. In recent years, foundation models…
Identifiability in Graphical Discrete Lyapunov Models
Cecilie Olesen Recke, Sarah Lumpp, Nataliia Kushnerchuk +4
In this paper, we study discrete Lyapunov models, which consist of steady-state distributions of first-order vector autoregressive models. The parameter matrix of such a model enco…
Breaking the Memory Wall: Exact Analytical Differentiation via Tiled Operator-Space Evolution
Shuhuan Wang, Yuzhen Xie, Jiayi Li +1
Selective State Space Models (SSMs) achieve linear-time inference, yet their gradient-based sensitivity analysis remains bottlenecked by O(L) memory scaling during backpropagation.…
Policy: Mutable Material Manipulation Augmentation Policy through Photometric Re-rendering
Jiayi Li, Yuxuan Hu, Haoran Geng +4
Material generalization is essential for real-world robotic manipulation, where robots must interact with objects exhibiting diverse visual and physical properties. This challenge…
Compact neural networks for astronomy with optimal transport bias correction
Shuhuan Wang, Yuzhen Xie, Jiayi Li
Astronomical imaging confronts an efficiency-resolution tradeoff that limits large-scale morphological classification and redshift prediction. We introduce WaveletMamba, a theory-d…
