Deep classifier kriging for probabilistic spatial prediction of air quality index
Junyu Chen, Pratik Nag, Huixia Judy-Wang +1
Accurate spatial interpolation of the air quality index (AQI), computed from concentrations of multiple air pollutants, is essential for regulatory decision-making, yet AQI fields…
OnlineSplatter: Pose-Free Online 3D Reconstruction for Free-Moving Objects
Mark He Huang, Lin Geng Foo, Christian Theobalt +2
Free-moving object reconstruction from monocular video remains challenging, particularly without reliable pose or depth cues and under arbitrary object motion. We introduce OnlineS…
Flow Matching-Based Active Learning for Radio Map Construction with Low-Altitude UAVs
Hao Sun, Shicong Liu, Xianghao Yu +1
The employment of unmanned aerial vehicles (UAVs) in the lowaltitude economy necessitates precise and real-time radio maps for reliable communication and safe navigation. However,…
Modeling nonstationary spatial processes with normalizing flows
Pratik Nag, Andrew Zammit-Mangion, Ying Sun
Nonstationary spatial processes can often be represented as stationary processes on a warped spatial domain. Selecting an appropriate spatial warping function for a given applicati…
