Researchers have developed a new trust-region based search algorithm (TRS) for aligning diffusion and flow models to specific rewards at inference time. This method treats the generative and reward models as black boxes, focusing solely on optimizing the source noise. TRS offers a balance between exploration and exploitation, requiring minimal hyperparameter tuning and proving versatile across various generative tasks like text-to-image generation, molecule design, and protein design. Evaluations show TRS significantly improves output samples compared to base models and other noise-optimization techniques. AI
