The paper proposes a novel approach to aligning Text-to-Image (T2I) conditional generation models with user intentions, achieving superior performance compared to state-of-the-art methods. The method relies on Mutual Information (MI) estimation between prompts and images, using self-supervised fine-tuning and a simple alignment strategy that maintains image quality. This achievement is notable as it only requires the pre-trained denoising network of the T2I model itself, making it a more efficient and practical solution.

Text-to-Image models are getting better at creating images from text descriptions, but they still need help to understand what we want them to generate. Researchers have been working on solving this problem, but so far, it’s been a bit like guessing – you try different approaches and see what works best. This new method uses something called Mutual Information (MI) to tell the model what kind of images to create based on the text description. It’s more accurate and efficient than previous methods, which is exciting news for people who want to use these models in real-world applications.
