FAST-LIVGO: A Degeneracy-Robust LiDAR-Inertial-Visual-GNSS Fusion Odometry
Zhiyu Chen, Chunran Zheng, Jiayu Wen +4
Robust state estimation and mapping in long-term, large-scale, and highly dynamic environments remains a key challenge in robotics. Existing LiDAR-Inertial-Visual Odometry (LIVO) s…
LIT-GS: LiDAR-Inertial-Thermal Gaussian Splatting for Illumination-Robust Mapping
Shikuan Shi, Chunran Zheng, Jiaming Xu +3
Gaussian Splatting has enabled real-time neural rendering, yet existing LiDAR-inertial-visual (LIV) Gaussian mapping pipelines remain fragile under illumination changes and texture…
All-or-Nothing Phenomena: From Single-Letter to High Dimensions
Galen Reeves, Jiaming Xu, Ilias Zadik
We consider the linear regression problem of estimating a -dimensional vector from observations , where for a real-val…
The All-or-Nothing Phenomenon in Sparse Linear Regression
Galen Reeves, Jiaming Xu, Ilias Zadik
We study the problem of recovering a hidden binary -sparse -dimensional vector from noisy linear observations where are i.i.d. an…
