Meet DreamSync: A New Artificial Intelligence Framework to Improve Text-to-Image (T2I) Synthesis with Feedback from Image Understanding Models

Researchers from the University of Southern California, the University of Washington, Bar-Ilan University, and Google Research introduced DreamSync, which addresses the problem of enhancing alignment and aesthetic appeal in diffusion-based text-to-image (T2I) models without the need for human annotation, model architecture modifications, or reinforcement learning. It achieves this by generating candidate images, evaluating them using Visual Question Answering (VQA) models, and fine-tuning the text-to-image model. Previous studies proposed using VQA models, exemplified by TIFA, to assess T2I generation. With 4K prompts and 25K questions, TIFA facilitates evaluation across 12 categories.
