In the Computational Creativity Lab, our approach for researching human creativity is developing and observing computer-generated works which externalize human creativity as a computational model rather than just observing things which were made by humans or the process of human creation itself. Specifically, we are researching and developing AI (Artificial Intelligence) that can perform and generate music, movies, and graphic design. By observing the things generated by these AI, we are able to explore what creativity is and how humans can extend their creativity by finding features and getting inspiration from the generated works.
