Abstract:
Diffusion models excel in generating diverse images but struggle with accurately capturing text prompts' intended meanings.
Predicated Diffusion proposes a unified framework using predicate logic to express users' intentions effectively.
It offers a differentiable loss function guiding image generation to fulfill propositions, outperforming existing methods.
Introduction:
Recent deep learning advancements have led to high-quality image generation, with diffusion models being stable and scalable.
Text-based image generation aims to generate faithful images from text prompts, where diffusion models like Stable Diffusion have made notable contributions.
Challenges in Text-Based Image Generation:
Existing methods often fail to capture the logical statements in prompts accurately, leading to missing objects, object mixture, attribute leakage, and possession failure.
Retraining diffusion models on large datasets is costly; hence guidance methods for pre-trained models are essential.
Method - Predicated Diffusion:
Represents relationships between words in prompts as propositions using predicate logic.
Utilizes attention maps and fuzzy logic to measure image fulfillment of propositions, guiding the image generation process effectively.
Experimental Results:
Predicated Diffusion outperforms other methods in addressing missing objects, attribute leakage, and possession failures.
Human evaluators found generated images more faithful to prompts with superior quality compared to existing methods.
