Learn to Triangulate Scene Coordinates for Visual Localization

Xiang Guo, Tianrui Chen, Bo Li, Qi Liu, Huarong Jia, Yuchao Dai

RA-L 2024

Visual localization plays a critical role in robotics. The scene coordinate regression-based localization methods have achieved state-of-the-art performance. However, current methods still have a gap between the regressed scene coordinates and the ground truth scene coordinates, which hinders the im

Strategies for Safe Multi-Armed Bandits with Logarithmic Regret and Risk

Tianrui Chen, Aditya Gangrade, Venkatesh Saligrama

ICML 2022spotlight

We investigate a natural but surprisingly unstudied approach to the multi-armed bandit problem under safety risk constraints. Each arm is associated with an unknown law on safety risks and rewards, and the learner’s goal is to maximise reward whilst not playing unsafe arms, as determined by a given…
