Introduction

Let's begin.

Contributions of this paper

  • Introduce a set of tasks that model natural feedback from a teacher and hence assess the feasibility of dialog-based language learning.
  • Evaluated some baseline models on this data and compared them to standard supervised learning.
  • Introduced a novel forward prediction model, whereby the learner tries to predict the teacher’s replies to its actions, which yields promising results, even with no reward signal at all
