Assessing creativity: The importance of unexpected novelty
Macedo, L., Cardoso, A.: Assessing creativity: The importance of unexpected novelty. In: Proceedings of the 2nd Workshop on Creative Systems (2002).
In this paper we experimentally study the contribution of theunexpectedness, unpredictability or surprising value of a novel productto its overall creative value. Accordingly, this creative value iscomputed within our approach through the use of a mathematicalfunction that relies on the contribution not only of novelty but also of unexpectedness. Implemented in artificial agents “living” in a multi-agent environment comprising objects such as buildings, this function,called within this context Utility Function, provides agents with amodel of its preferences when evaluating a product, and thus allowingthem to prefer those products that elicit more surprise (elicited byunexpectedness) and curiosity (elicited by novelty andunexpectedness). We performed a series of experimental tests thatinvolved an artificial agent and humans in order to take conclusionsabout the nature of that mathematical function, and also about thecontribution of unexpectedness to it.
