• Title: From Image to UML: First Results of Image Based UML Diagram Generation Using LLMs
• Authors: Aaron Conrardy, Jordi Cabot,
• Abstract summary: In software engineering processes, systems are first specified using a modeling language. Large Language Models (LLM) are used to generate the formal representation of (UML) models from a given drawing. More specifically, we have evaluated the capabilities of different LLMs to convert images of class diagrams into the actual models represented in the images.

• Abstract: In software engineering processes, systems are first specified using a modeling language such as UML. These initial designs are often collaboratively created, many times in meetings where different domain experts use whiteboards, paper or other types of quick supports to create drawings and blueprints that then will need to be formalized. These proper, machine-readable, models are key to ensure models can be part of automated processes (e.g. input of a low-code generation pipeline, a model-based testing system, ...). But going from hand-drawn diagrams to actual models is a time-consuming process that sometimes ends up with such drawings just added as informal images to the software documentation, reducing their value a lot. To avoid this tedious task, we explore the usage of Large Language Models (LLM) to generate the formal representation of (UML) models from a given drawing. More specifically, we have evaluated the capabilities of different LLMs to convert images of UML class diagrams into the actual models represented in the images. While the results are good enough to use such an approach as part of a model-driven engineering pipeline we also highlight some of their current limitations and the need to keep the human in the loop to overcome those limitations.

  In real-world domain modeling, engineers usually decompose complex tasks into easily solvable sub-tasks. We propose an LLM-based domain modeling approach via question decomposition, similar to developer's modeling process. Preliminary results show that our approach outperforms the single-prompt-based prompt.

  Two models, DALL-E 2 and Imagen, have demonstrated that highly photorealistic images could be generated from a simple textual description of an image. Text-to-image models require exceptionally large amounts of computational resources to train, as well as handling huge datasets collected from the internet. This thesis contributes by reviewing the different approaches and techniques used by these models, and then by proposing our own implementation of a text-to-image model.

  Internal learning for single-image generation is a framework, where a generator is trained to produce novel images based on a single image. We propose a meta-learning approach that enables training over a collection of images, in order to model the internal statistics of the sample image more effectively. Our results show that the models obtained are as suitable as single-image GANs for many common image applications.
