Betting for Sim-to-Real Performance Certificates
Yujia Chen, Bowen Weng
Consider a typical test of a robot system: one observes a sequence of outcomes concerning some aspect of interest (crash or no crash, tracking error, time to completion), and repor…
Sim-to-Real Betting on the E-Process: Bringing "simulators" to anytime-valid confidence sequences
Yujia Chen, Bowen Weng
This note describes an integration of the sim-to-real performance estimate with betting (from Chen et al.) and the safe anytime-valid inference (from Ramdas et al.). Using the scal…
Betting for Sim-to-Real Performance Evaluation
Zaid Mahboob, Yujia Chen, Bowen Weng
This paper studies the problem of robot performance evaluation, focusing on how to obtain accurate and efficient estimates of real-world behavior under severe constraints on physic…
Thermal odometry and dense mapping using learned odometry and Gaussian splatting
Tianhao Zhou, Yujia Chen, Zhihao Zhan +2
Thermal infrared sensors, with wavelengths longer than smoke particles, can capture imagery independent of darkness, dust, and smoke. This robustness has made them increasingly val…
