Combining Evolutionary Search and Generative AI to Enable Creativity in Conceptual Architecture

Core Concepts
SCAPE combines evolutionary search with generative AI, enabling users to explore creative and high-quality architectural designs inspired by their initial input through a simple point and click interface.
The paper introduces SCAPE (Searching Conceptual Architecture Prompts using Evolution), a tool that combines evolutionary search with generative AI to enable creativity in conceptual architecture design. Key highlights: SCAPE injects randomness into generative AI systems like DALL·E 3 and leverages the language skills of GPT-4 to enable text-based mutation and crossover. Compared to vanilla DALL·E 3, SCAPE enables a 67% improvement in image novelty, plus improvements in quality and effectiveness of use. In just three iterations, SCAPE achieves a 24% increase in image novelty, enabling effective exploration and optimization of images by users. Over 20 independent architects provided markedly positive feedback on SCAPE, suggesting it is a valuable tool for conceptual architecture. SCAPE makes use of GPT-4 and DALL·E 3 as the current state-of-the-art generative AI models, combining their strengths to address the needs of conceptual architecture.

How could SCAPE be extended to incorporate user-defined architectural attributes or allow sketching as an input modality?

To incorporate user-defined architectural attributes into SCAPE, the system could be enhanced to allow users to input specific attributes that are relevant to their architectural design concept. This could involve providing users with a set of predefined attributes or allowing them to input custom attributes. The attributes provided by the user could then be integrated into the genetic representation of the system, enabling the evolution process to consider these user-defined attributes when generating new designs. Additionally, to enable sketching as an input modality, SCAPE could be updated to accept image inputs in the form of sketches. Users could sketch their architectural concepts, which would then be processed by the system to extract relevant attributes or features. These extracted attributes could be used as input for the evolutionary algorithm, guiding the generation of architectural designs based on the user's sketches.

What are the potential limitations or biases introduced by using large language models like GPT-4 for prompt engineering and mutation/crossover operations?

While large language models like GPT-4 offer significant capabilities for natural language processing and generation, there are potential limitations and biases that can arise when using them for prompt engineering and mutation/crossover operations in systems like SCAPE. Prompt Engineering Limitations: Large language models may struggle with understanding nuanced or complex prompts, leading to misinterpretations or incomplete generation of attributes. This can result in inaccuracies in the prompt-based evolution process. Biases in Language Generation: GPT-4, like other language models, may exhibit biases present in the training data, which can influence the attributes or descriptions generated during mutation/crossover operations. Biased language generation can impact the diversity and quality of the designs produced by the system. Limited Creativity: While GPT-4 is proficient at generating coherent text, it may lack the creativity and innovation demonstrated by human designers or evolutionary algorithms. This limitation can affect the novelty and originality of the architectural designs generated by SCAPE. Dependency on Training Data: The performance of GPT-4 is heavily reliant on the quality and diversity of its training data. Biases or limitations present in the training data can propagate into the prompt engineering and mutation/crossover processes, potentially constraining the range of outputs.

How might SCAPE's approach of combining evolutionary search and generative AI be applied to other creative domains beyond architecture?

SCAPE's innovative approach of combining evolutionary search with generative AI can be extended to various other creative domains beyond architecture to facilitate novel idea generation and exploration. Here are some potential applications: Fashion Design: SCAPE could be adapted to assist fashion designers in creating unique clothing designs by evolving attributes such as fabric types, colors, patterns, and styles. Users could input initial concepts or sketches, and the system could generate diverse fashion designs for exploration. Product Design: In product design, SCAPE could help in generating innovative product concepts by evolving attributes related to functionality, aesthetics, materials, and user experience. This approach could streamline the design ideation process and lead to the creation of novel product designs. Interior Design: SCAPE's methodology could be applied to interior design to generate creative interior layouts, furniture designs, color schemes, and decor elements. Users could input preferences or sketches, and the system could evolve designs that align with their vision. Landscape Architecture: For landscape architects, SCAPE could be utilized to explore diverse landscaping ideas, plant arrangements, hardscape features, and thematic elements. By combining evolutionary search with generative AI, the system could assist in creating innovative landscape designs. By adapting SCAPE's framework to these creative domains, designers and creators can leverage the power of evolutionary algorithms and generative AI to enhance their ideation processes, foster creativity, and discover unique design solutions.
