However, it can be challenging to produce creative ideas that will be of value to society and worthy of design effort. This thesis explores combinational creativity, which involves unfamiliar combinations of familiar ideas, and implements combinational creativity in computational tools to support design. Two computational tools, the Combinator and the Retriever, have been developed to support designers in creative idea generations during the early stages of design. The Combinator has been developed by imitating aspects of human cognition in achieving combinational creativity. This tool produces combinational prompts in text and image forms. The Retriever has been developed based on ontology by embracing aspects of cognitions of analogical reasoning. This tool constructs ontologies with sufficient richness and coverage to support reasoning over real-world datasets, and produces text-form outputs with correlated image mood boards. Case studies indicate that the Combinator and the Retriever are useful and effective in terms of supporting creative ideation. The case studies show that both of the tools can increase the fluency of idea generation and improve the flexibility, usefulness and originality of the ideas produced, for the datasets studied. In addition to computational creativity tools, this thesis has proposed three driven approaches to produce combinational creative ideas, which are problem-, similarity-, and inspiration-driven. A study indicates that these three approaches are used commonly in practical designs, of which the problem-driven approach is the dominant approach. In addition, the three approaches could be used individually as well as in groups. The conceptual distances between ideas in combinational creativity are also explored in this thesis. A study reveals that far-related ideas, which are used more commonly, could lead to more creative outcomes compared with closely-related ideas. The findings and outcomes of this thesis lead to a further understanding of creativity in the design context. The novel approaches used for developing the Combinator and the Retriever, as well as the outcomes of the theoretical studies could be adapted to develop new computational design support tools.

Such creative software can be used for autonomous creative tasks, such as inventing mathematical the- ories, writing poems, painting pictures, and composing music. However, computational creativity studies also enable us to understand human creativity and to produce programs for cre- ative people to use, where the software acts as a creative collab- orator rather than a mere tool. Historically, it’s been difficult for society to come to terms with machines that purport to be intel- ligent and even more difficult to admit that they might be cre- ative. For instance, in 1934, some professors at the University of Manchester in the United Kingdom built meccano models that were able to solve some mathematical equations. Groundbreak- ing for its time, this project was written up in a piece in Mecca- no Magazine. The article was titled “Are Thinking Machines Pos- sible” and was very upbeat, but surprisingly ends by stating that “Truly creative thinking of course will always remain beyond the power of any machine.” Surely, though, this attitude has changed in light of the amaz- ing advances in hardware and software technology that fol- lowed those meccano models? Sadly, no.

  • The Computational Creativity Complex
    The Computational Creativity Complex Dan Ventura Abstract We briefly examine the subject of computational creativity through the lenses of three different systems for producing creative artifacts in three different domains: music, visual art and cookery. From these we attempt to abstract some- thing of a “general-purpose” computationally creative agent and examine how this agent might behave in the context of an archetypical “algorithm” for creativity. Fi- nally, we consider this agent’s behavior from the point of view of the theory of (Turing) computability and suggest that computational creativity as a field provides an interesting opportunity for looking at computational complexity in new ways. 1 Inception The question of computational creativity can be approached from several different angles. Here we assume that creativity is possible in computational systems and examine the idea of a general, abstract mechanism for computational creativity that exists somehow independently from any particular domain. This is a difficulty ques- tion, and it is clear that much of creativity is not a domain independent construct. However, we posit that there does exist some core abstraction or creativity “algo- rithm” that can be applied to any domain (with suitable domain-specific augmen- tation, of course). Given this hypothesis, we attempt an inductive approach to the problem by first examining three computationally creative systems in three differ- ent domains and then attempt to generalize from these specific examples an abstract model of a creative system. As a complementary view of the problem, we also discuss an abstract “al- gorithm” for creativity and relate this “algorithm” to the abstract system, asking whether this “algorithm” could, in fact, become an algorithm in the formal sense, Dan Ventura Computer Science Department, Brigham Young University, e-mail: [email protected] 1 2 Dan Ventura and attempt to reason about the answer to that question.

  • A Critical Review of Computational Creativity in Built Environment Design
    buildings Review A Critical Review of Computational Creativity in Built Environment Design Ning Gu * and Peiman Amini Behbahani UniSA Creative, University of South Australia, Adelaide 5001, Australia; [email protected] * Correspondence: [email protected] Abstract: Computational creativity in built environment (BE) design has been a subject of research interest in the discipline. This paper presents a critical review of various ways computational creativ- ity has been and can be defined and approached in BE design. The paper examines a comprehensive body of contemporary literature on the topics of creativity, computational creativity, and their assess- ment to identify levels of computational creativity. The paper then proceeds to a further review of the implications of these levels specifically in BE design. The paper identifies four areas in BE design where computational creativity is relevant. In two areas—synthesis (generation) and analysis—there is considerable literature on lower levels of computational creativity. However, in two other areas— interfacing and communication—even the definition of computational creativity is not as defined and clear for the discipline, and most works only consider the role of computers as a supporting tool or medium. These open up future research opportunities for the discipline. Keywords: computational creativity; human–computer (co-)creativity; creativity support tools; built environment design 1.

  • Artistic Creativity in Artificial Intelligence
    Artistic Creativity in Artificial Intelligence a dissertation presented by Deniz E. Kurt to The Department of Creative Industries in partial fulfillment of the requirements for the degree of Master of Arts in the subject of Arts & Culture Radboud University Nijmegen, Netherlands April 2018 ©2018 – Deniz E. Kurt all rights reserved. Thesis advisor: Dr. Vincent Meelberg Deniz E. Kurt Artistic Creativity in Artificial Intelligence Abstract Computational art is a creative field that indicates to a futuristic idea of artificial intelligence. De- spite the common belief that a machine is unable to create art, current developments and examples in computational art present a new form of art. Reaching to a broad variety of artistic dimensions, artificial intelligence programs are generating poetry, music, visual art, architecture and design. This study introduces artificial intelligence as an artistic phenomenon and analyzes the artifacts that are produced by computer algorithms. Thus, it provides a theoretical framework and a philosophical dis- cussion on the creative abilities of artificial intelligence. Furthermore, it concerns with the entitlement of artiness, by presenting a reflection on the dynamics between the artwork, the art-maker and the art audience. The analysis of computational artworks and the computer programs that generate those artworks show that the function of artificial intelligence is far beyond being merely a tool to create art, it is rather an actor that have an artistic and creative agency. With this study, I suggest an alternative approach in the conceptual definition of art, which can help to explore the possibilities of a new art genre. iii Contents 0 Introduction 1 1 Human Intelligence vs.

  • Associative Algorithms for Computational Creativity
    LAV R. VARSHNEY JUN WANG KUSH R. VARSHNEY Special Issue on Creativity and Food Associative Algorithms for Computational Creativity ABSTRACT Computational creativity, the generation of new, unimagined ideas or artifacts by a machine that are deemed creative by people, can be applied in the culinary domain to create novel and flavorful dishes. In fact, we have done so successfully using a combina- torial algorithm for recipe generation combined with statistical models for recipe ranking and selection. However, the algorithm of creation in our prior work may be difficult for people to interpret, understand, and ultimately adopt because the process differs from the process of human creativity theorized in the psychology and neuroscience literatures. In this paper, to address this issue, we discuss how human creativity, including in the food arena, may be built on associations and how an algorithm also built on associations can be more relatable to people so they can interact with the tool more easily. We pro- pose a computational creativity approach that extends the data mining technique of asso- ciation rule mining to generate new food recipes. We illustrate this associative algorithm on real-world culinary data. Keywords: association mining, computational creativity, food. Computational creativity is the use of computers to generate and select ideas or arti- facts that would be regarded as creative if produced by people alone. This area of study has a long history with workers motivated by disparate goals. Some researchers are after scientific understanding of the mind, whereas others have the technological goal of pro- ducing useful tools; some practitioners may try to illuminate the psychological processes underlying creativity, whereas others try to produce esthetically interesting results (Boden, 2015).
