Pretraining with Artificial Language: Studying Transferable Knowledge in Language Models

Ryokan Ri, Yoshimasa Tsuruoka

We investigate what kind of structural knowledge learned in neural network encoders is transferable to processing natural language. We design artificial languages with structural p…

Off-Policy Meta-Reinforcement Learning Based on Feature Embedding Spaces

Takahisa Imagawa, Takuya Hiraoka, Yoshimasa Tsuruoka

Meta-reinforcement learning (RL) addresses the problem of sample inefficiency in deep RL by using experience obtained in past tasks for a new task to be solved. However, most meta-…
