CHATS: Combining Human-Aligned Optimization and Test-Time Sampling for Text-to-Image Generation

ICML 2025poster

Diffusion models have emerged as a dominant approach for text-to-image generation. Key components such as the human preference alignment and classifier-free guidance play a crucial role in ensuring generation quality. However, their independent application in current text-to-image models continues t…

TeEFusion: Blending Text Embeddings to Distill Classifier-Free Guidance

ICCV 2025poster

Recent advances in text-to-image synthesis largely benefit from sophisticated sampling strategies and classifier-free guidance (CFG) to ensure high-quality generation. However, CFG's reliance on two forward passes, especially when combined with intricate sampling algorithms, results in prohibitively…
