About
Attend-and-Excite is the official implementation for "Attend-and-Excite: Attention-Based Semantic Guidance for Text-to-Image Diffusion Models" (SIGGRAPH 2023). This open-source tool addresses common failure cases in state-of-the-art diffusion models, such as catastrophic neglect where models fail to generate all subjects from an input prompt, or incorrectly bind attributes. It introduces Generative Semantic Nursing (GSN) to intervene during inference time, improving image faithfulness. Specifically, Attend-and-Excite guides the model to refine cross-attention units, ensuring all subject tokens in the text prompt are attended to and their activations are strengthened, leading to more semantically accurate image generation. It builds upon and enhances existing models like Stable Diffusion, providing a method to generate images that more faithfully depict the input text prompt.
