On the Weaknesses of Reinforcement Learning for Neural Machine Translation

no code implementations ICLR 2020 Leshem Choshen, Lior Fox, Zohar Aizenbud, Omri Abend

Reinforcement learning (RL) is frequently used to increase performance in text generation tasks, including machine translation (MT), notably through the use of Minimum Risk Training (MRT) and Generative Adversarial Networks (GAN).

DORA The Explorer: Directed Outreaching Reinforcement Action-Selection

1 code implementation ICLR 2018 Leshem Choshen, Lior Fox, Yonatan Loewenstein

We compare our approach to commonly used RL techniques, and show that using $E$-values improves learning and performance over traditional counters.
