Decision-Making Among Bounded Rational Agents

no code implementations17 Oct 2022 Junhong Xu, Durgakant Pushp, Kai Yin, Lantao Liu

Using both simulated and real-world experiments in multi-robot navigation tasks, we demonstrate that the resulting framework allows the robots to reason about different levels of rational behaviors of other agents and compute a reasonable strategy under its computational constraint.

Online Planning in Uncertain and Dynamic Environment in the Presence of Multiple Mobile Vehicles

no code implementations8 Sep 2020 Junhong Xu, Kai Yin, Lantao Liu

We first predict the future state distributions of other vehicles to account for their uncertain behaviors affected by the time-varying disturbances.

Kernel Taylor-Based Value Function Approximation for Continuous-State Markov Decision Processes

no code implementations3 Jun 2020 Junhong Xu, Kai Yin, Lantao Liu

We propose a principled kernel-based policy iteration algorithm to solve the continuous-state Markov Decision Processes (MDPs).

Reachable Space Characterization of Markov Decision Processes with Time Variability

no code implementations22 May 2019 Junhong Xu, Kai Yin, Lantao Liu

We propose a solution to a time-varying variant of Markov Decision Processes which can be used to address decision-theoretic planning problems for autonomous systems operating in unstructured outdoor environments.

Shared Multi-Task Imitation Learning for Indoor Self-Navigation

no code implementations14 Aug 2018 Junhong Xu, Qiwei Liu, Hanqing Guo, Aaron Kageza, Saeed AlQarni, Shaoen Wu

Deep imitation learning enables robots to learn from expert demonstrations to perform tasks such as lane following or obstacle avoidance.

Avoidance of Manual Labeling in Robotic Autonomous Navigation Through Multi-Sensory Semi-Supervised Learning

no code implementations22 Sep 2017 Junhong Xu, Shangyue Zhu, Hanqing Guo, Shaoen Wu

This solution includes a suboptimal sensor policy based on sensor fusion to automatically label states encountered by a robot to avoid human supervision during training.
