Collaboration in Co-Creative Scenarios via Coupled Empowerment Maximization: A Case-Study in Video Games

This talk was given on 10th February 2016 by a guest speaker, Christian Guckelsburger from Goldsmiths University of London.

Recently, embodied and situated agents have become increasingly popular in co-creative systems (where humans and artificial agents jointly work on creative tasks). Intrinsically-motivated agents are particularly successful here, because of their capacity to act flexibly and adapt in open-ended interactions without clearly specified goals. Unfortunately, existing implementations do not manage to establish and maintain collaboration as a core mechanic in such systems without constraining the flexibility of the agents by means of explicitly specified interaction rules. This talk introduces the information-theoretic principle of coupled empowerment maximization as a means to establish a frame for both collaborative and antagonistic behaviour within which agents can interact with maximum flexibility. We study this mechanism in a dungeon-crawler video game testbed, to drive the behavior of an NPC supporting the human player. We demonstrate our progress, future challenges, and argue that the principle could eventually allow for the emergence of truly creative behavior.
