Learning to control an environment without hand-crafted rewards or expert data remains challenging and is at the frontier of reinforcement learning research.

It has been established that diverse behaviors spanning the controllable subspace of an Markov decision process can be trained by rewarding a policy for being distinguishable from other policies \citep{gregor2016variational, eysenbach2018diversity, warde2018unsupervised}.

Q-Learning in enormous action spaces via amortized approximate maximization

no code implementations • 22 Jan 2020 • Tom Van de Wiele, David Warde-Farley, andriy mnih, Volodymyr Mnih

Applying Q-learning to high-dimensional or continuous action spaces can be difficult due to the required maximization over the set of possible actions.
