XFreq-GS: Cross-Frequency Wireless Radiation Field Reconstruction with 3D Gaussian Splatting
Sheng Wang, Hengtao He, Chaozheng Wen +5
Channel modeling is fundamental to the analysis, design, and optimization of wireless communication systems, which, however, accurate wireless channel modeling remains challenging,…
Signature Approach for Contextual Bandits with Nonlinear and Path-dependent Rewards
Xin Guo, Grace He, Xinyu Li
We study contextual bandits with nonlinear and path-dependent rewards through a novel signature-transform-based approach. Leveraging the universal nonlinearity property of signatur…
Fast Policy Learning for Linear Quadratic Control with Entropy Regularization
Xin Guo, Xinyu Li, Renyuan Xu
This paper proposes and analyzes two new policy learning methods: regularized policy gradient (RPG) and iterative policy optimization (IPO), for a class of discounted linear-quadra…
Transportation Marketplace Rate Forecast Using Signature Transform
Haotian Gu, Xin Guo, Timothy L. Jacobs +2
Freight transportation marketplace rates are typically challenging to forecast accurately. In this work, we have developed a novel statistical technique based on signature transfor…
