Researchers have developed a new method called Alignment-Guided Score Matching to improve the accuracy of text-to-image generation in diffusion models. This technique refines soft text tokens by integrating contrastive alignment guidance directly into the score-matching objective, addressing limitations of previous contrastive learning approaches that could lead to over-counting and repetition. The proposed method achieves comparable results to existing techniques like SoftREPA while significantly reducing failure cases, demonstrating over a 35% improvement in counting accuracy on the GenEval benchmark. This approach is compatible with various diffusion model backbones, including SD1.5, SDXL, and SD3, and can complement reinforcement learning-based post-training methods. AI
