Most convergence results for TD methods rely on the assumption that the underlying environment is Markovian; the paper by Schapire and Warmuth shows that, even for environments that are arbitrarily non-Markovian ...
The problem of exploration in unknown environments is a crucial one for reinforcement learning. ...

Interactive reinforcement learning has allowed speeding up the learning process in autonomous agents by including a human trainer providing extra information to the agent in real-time. ...
In this work, we propose a persistent rule-based interactive reinforcement learning approach, i.e., a method for retaining and reusing provided knowledge, allowing trainers to give general advice relevant ...
Introduction Interactive reinforcement learning (IntRL) allows a trainer to guide or evaluate a learning agent's behaviour [1, 2] . ...

The XCS learning classifier system uses a fixed explore/exploit balance, but does keep multiple statistics about its performance and interaction in an environment. ...
In reinforcement learning problems it has been considered that neither exploitation nor exploration can be pursued exclusively without failing at the task. ...

QRM is guaranteed to converge to an optimal policy in the tabular case, in contrast to Hierarchical Reinforcement Learning methods which might converge to suboptimal policies. ...
We also show how function approximation methods like neural networks can be incorporated into QRM, and that doing so can find better policies more quickly than hierarchical methods in a domain with a continuous ...
Note that the rewards the agent gets may be non-Markovian relative to the environment (the states of S), though they are Markovian relative to the elements in S × U . ...

In continuing tasks, average-reward reinforcement learning may be a more appropriate problem formulation than the more common discounted reward formulation. ...
Reward shaping is a common approach for incorporating domain knowledge into reinforcement learning in order to speed up convergence to an optimal policy. ...
We are also interested in expanding the learning problem to include both non-Markovian reward structures and shaping functions. ...
