  1. Computational Artistic Creativity and its Evaluation DAVID C BROWN Computer Science Department WPI, Worcester, MA 01609, USA <dcb@cs.wpi.edu>

  2. Motivation • “What are the appropriate methods and measures to objectively verify and validate creative behavior in artificial systems?” • Evaluation by people • Evaluation by computational system • Evaluation ofartifact • Evaluation of process

  3. Your Research Goals? • Producing creative artifacts using computational means. • Study what knowledge and reasoning might be part of process that produces creative artifacts. • Study the criteria that a person or a system might use to judge whether an item is creative or not.

  4. Your Research Goals?(continued) 4. Produce a formal theory of creativity. 5. Produce new “computational means”.

  5. Creativity Evaluation • How to judge impact of decision or quality of partial solution during synthesis? • E.g., using constraint to reduce search space • How to judge artifact (or its description)?

  6. Necessary or Helpful? • Is it necessary for system to evaluate during synthesis and/or evaluate the resulting artifact? • If not, is it helpful?

  7. Criteria? What factors are used to evaluate creativity?

  8. Examples • Besemer has 3 factors in the Creative Product Analysis Model. • Abrams has 4 ways of considering the analysis, criticism or evaluation of art.

  9. Besemer’s CPAM:Creative Product Analysis Model • Factors: Novelty, Resolution & Style • Novelty: newness • Surprising, Original • Resolution: meets needs • Logical, Useful, Valuable, Understandable • Style: refined, developed, coherent whole • Organic, Well-Crafted, Elegant

  10. Abrams • Mimetic - imitating aspects of the observable universe, but not artifact, artist or audience. • Pragmatic - the relationship between the artifact and audience, including teaching & producing emotional reactions. • Expressive - externalizing artist’s inner life. • Objective - viewing artifact in isolation. • Combinations are possible.

  11. Some Computational Challenges • Surprising: what is “normal” art? • Useful: what is purpose of the artifact? • Valuable: knowledge of art market? • Understandable: user friendly art? • Pragmatic: does it provoke emotion? • Expressive: artist’s “inner life”?

  12. Overall Challenge A Computational Artistic Creativity system must be able to evaluate its own output for creativity, and be able to evaluate its decisions and partial solutions for creative potential.

  13. Conclusions • For Computational Design Creativity systems that design products I thinkthis is possible. • For Computational Artistic Creativity systems I have very grave doubts. 8 July 2009
