The UIClip model can be enhanced to handle more complex and diverse GUI elements by incorporating additional training data that includes wireframes and sketches. By expanding the dataset to include a variety of GUI representations, the model can learn to extract features and patterns from different types of visual elements. Additionally, fine-tuning the model on datasets specifically focused on wireframes and sketches can help UIClip better understand the unique characteristics and structures of these elements. Furthermore, incorporating domain-specific knowledge and features related to wireframes and sketches into the training process can improve the model's ability to accurately retrieve and interpret such GUI elements.
