Spatiotemporal Attention Enhances Lidar-Based Robot Navigation in Dynamic Environments
Jorge de Heuvel, Xiangyu Zeng, Weixian Shi +2
Foresighted robot navigation in dynamic indoor environments with cost-efficient hardware necessitates the use of a lightweight yet dependable controller. So inferring the scene dyn…
Subgoal-Driven Navigation in Dynamic Environments Using Attention-Based Deep Reinforcement Learning
Jorge de Heuvel, Weixian Shi, Xiangyu Zeng +1
Collision-free, goal-directed navigation in environments containing unknown static and dynamic obstacles is still a great challenge, especially when manual tuning of navigation pol…
Single View Physical Distance Estimation using Human Pose
Xiaohan Fei, Henry Wang, Xiangyu Zeng +3
We propose a fully automated system that simultaneously estimates the camera intrinsics, the ground plane, and physical distances between people from a single RGB image or video ca…
User Information Augmented Semantic Frame Parsing using Coarse-to-Fine Neural Networks
Yilin Shen, Xiangyu Zeng, Yu Wang +1
Semantic frame parsing is a crucial component in spoken language understanding (SLU) to build spoken dialog systems. It has two main tasks: intent detection and slot filling. Altho…
Learning Speech Rate in Speech Recognition
Xiangyu Zeng, Shi Yin, Dong Wang
A significant performance reduction is often observed in speech recognition when the rate of speech (ROS) is too low or too high. Most of present approaches to addressing the ROS v…
