Divide-Then-Aggregate: An Efficient Tool Learning Method via Parallel Tool Invocation

ACL 2025long

While Large Language Models (LLMs) demonstrate remarkable capabilities, their ability to autonomously execute complex real-world tasks remains limited. Accordingly, tool learning has emerged to enable LLMs to effectively leverage external tools to extend their capabilities. Current tool-learning par…

Spatiotemporal Attention Enhances Lidar-Based Robot Navigation in Dynamic Environments

RA-L 2024

Foresighted robot navigation in dynamic indoor environments with cost-efficient hardware necessitates the use of a lightweight yet dependable controller. So inferring the scene dynamics from sensor readings without explicit object tracking is a pivotal aspect of foresighted navigation among pedestri

Enhanced Spatial Attention Graph for Motion Planning in Crowded, Partially Observable Environments

ICRA 2022poster

Collision-free navigation while moving amongst static and dynamic obstacles with a limited sensor range is still a great challenge for modern mobile robots. Therefore, the ability to avoid collisions with obstacles in crowded, partially observable environments is one of the most important indicators…
