LTL and Beyond: Formal Languages for Reward Function Specification in Reinforcement Learning
In Reinforcement Learning (RL), an agent is guided by the rewards it receives from the reward function. Unfortunately, it may take many …
Teaching Multiple Tasks to an RL Agent using LTL
This paper examines the problem of how to teach multiple tasks to a Reinforcement Learning (RL) agent. To this end, we use Linear …
Using Reward Machines for High-Level Task Specification and Decomposition in Reinforcement Learning
In this paper we propose Reward Machines – a type of finite state machine that supports the spec- ification of reward functions while …
Advice-Based Exploration in Model-Based Reinforcement Learning
Convergence to an optimal policy using model-based rein- forcement learning can require significant exploration of the environment. In …
LLMs can learn self-restraint through iterative self-reflection
In order to be deployed safely, Large Language Models (LLMs) must be capable of dynamically adapting their behavior based on their …
