listening to reinforcement learning

This experimental project investigated how people perceive behaviours of reinforcement learning through sound.

Reinforcement learning defines a formal framework for the interaction between a learning agent and an environment in terms of states, actions, and rewards. Our interest situated in interactive approaches to reinforcement learning, where the agent directly receives the reward signal from human feedback. Such an expressive workflow could allow humans to teach agents specific behaviours based on subjective preferences.

We were interested in studying how people may perceive agent behaviour through sound listening during feedback-based teaching. We thus led a controlled experiment where we asked participants to guide three types of agents using only feedback, in two sound synthesis environment. Participants successfully interacted with these agents to reach a sonic goal in two cases of different complexities. Subjective evaluations suggest that the exploration path taken by agents, rather than the fact of reaching a goal, may be critical to how agents are perceived as collaborative.
