Highly Efficient Test-Time Scaling for T2I Diffusion Models with Text Embedding Perturbation

Hang Xu, Linjiang Huang, Feng Zhao

Test-time scaling (TTS) aims to achieve better results by increasing random sampling and evaluating samples based on rules and metrics. However, in text-to-image(T2I) diffusion mod…
