Verifiable and Compositional Reinforcement Learning Systems [article]

Cyrus Neary, Christos Verginis, Murat Cubuktepe, Ufuk Topcu
2022 arXiv   pre-print
We propose a framework for verifiable and compositional reinforcement learning (RL) in which a collection of RL subsystems, each of which learns to accomplish a separate subtask, are composed to achieve  ...  This in turn allows for the independent training and testing of the subsystems; if they each learn a policy satisfying the appropriate subtask specification, then their composition is guaranteed to satisfy  ...  Acknowledgements This work was supported in part by ONR N00014-20-1-2115, ARO W911NF-20-1-0140, and NSF 1652113.  ...

Cumulative Learning Through Intrinsic Reinforcements [chapter]

Vieri G. Santucci, Gianluca Baldassarre, Marco Mirolli
2014 Evolution, Complexity and Artificial Life  
We compare different versions of the system varying the composition of the learning signal and we show that the only system able to reach high performance in the task is the one that implements the learning  ...  In particular, we suggest that the particular composition of such a signal, determined by both extrinsic and intrinsic reinforcements, would be suitable to improve the implementation of cumulative learning  ...  We varied the composition of the learning signal and we verified that only the one implementing our hypothesis was able to guide the simulated robot in the achievement of the task.  ...
