The Planner Optimization Problem: Formulations and Frameworks

no code implementations12 Mar 2023 Yiyuan Lee, Katie Lee, Panpan Cai, David Hsu, Lydia E. Kavraki

Identifying internal parameters for planning is crucial to maximizing the performance of a planner.

MAGIC: Learning Macro-Actions for Online POMDP Planning

1 code implementation7 Nov 2020 Yiyuan Lee, Panpan Cai, David Hsu

The partially observable Markov decision process (POMDP) is a principled general framework for robot decision making under uncertainty, but POMDP planning suffers from high computational complexity, when long-term planning is required.

GAMMA: A General Agent Motion Model for Autonomous Driving

1 code implementation4 Jun 2019 Yuanfu Luo, Panpan Cai, Yiyuan Lee, David Hsu

Further, the computational efficiency and the flexibility of GAMMA enable (i) simulation of mixed urban traffic at many locations worldwide and (ii) planning for autonomous driving in dense traffic with uncertain driver behaviors, both in real-time.
