Motif: Intrinsic Motivation from Artificial Intelligence Feedback

Klissarov, Martin, D'Oro, Pierluca, Sodhani, Shagun et al.

Understand

Exploring rich environments and evaluating one's actions without prior knowledge is immensely challenging.

  • In this paper, we propose Motif, a general method to interface such prior knowledge from a Large Language Model (LLM) with an agent.
  • Motif is based on the idea of grounding LLMs for decision-making without requiring them to interact with the environment: it elicits preferences from an LLM over pairs of captions to construct an intrinsic reward, which is then used to train agents with reinforcement learning.
  • We evaluate Motif's performance and behavior on the challenging, open-ended and procedurally-generated NetHack game.
