Model-based Lifelong Reinforcement Learning with Bayesian Exploration

2 code implementations20 Oct 2022 Haotian Fu, Shangqun Yu, Michael Littman, George Konidaris

We propose a model-based lifelong reinforcement-learning approach that estimates a hierarchical Bayesian posterior distilling the common structure shared across different tasks.

Meta-Learning Parameterized Skills

1 code implementation7 Jun 2022 Haotian Fu, Shangqun Yu, Saket Tiwari, Michael Littman, George Konidaris

We propose a novel parameterized skill-learning algorithm that aims to learn transferable parameterized skills and synthesize them into a new action space that supports efficient learning in long-horizon tasks.

Hierarchical Reinforcement Learning of Locomotion Policies in Response to Approaching Objects: A Preliminary Study

no code implementations20 Mar 2022 Shangqun Yu, Sreehari Rammohan, Kaiyu Zheng, George Konidaris

Animals such as rabbits and birds can instantly generate locomotion behavior in reaction to a dynamic, approaching object, such as a person or a rock, despite having possibly never seen the object before and having limited perception of the object's properties.

Learning Generalizable Behavior via Visual Rewrite Rules

no code implementations9 Dec 2021 Yiheng Xie, Mingxuan Li, Shangqun Yu, Michael Littman

Though deep reinforcement learning agents have achieved unprecedented success in recent years, their learned policies can be brittle, failing to generalize to even slight modifications of their environments or unfamiliar situations.

Bayesian Exploration for Lifelong Reinforcement Learning

no code implementations29 Sep 2021 Haotian Fu, Shangqun Yu, Michael Littman, George Konidaris

A central question in reinforcement learning (RL) is how to leverage prior knowledge to accelerate learning in new tasks.

Value-Based Reinforcement Learning for Continuous Control Robotic Manipulation in Multi-Task Sparse Reward Settings

no code implementations28 Jul 2021 Sreehari Rammohan, Shangqun Yu, Bowen He, Eric Hsiung, Eric Rosen, Stefanie Tellex, George Konidaris

Learning continuous control in high-dimensional sparse reward settings, such as robotic manipulation, is a challenging problem due to the number of samples often required to obtain accurate optimal value and policy estimates.
