Researchers have developed a novel method for learning dynamic guidance schedules in text-to-image diffusion models. Current models often use a static, global guidance scale, which can be suboptimal and lead to artifacts. This new approach trains a discriminator to estimate the time-dependent density ratio between true and guided distributions, allowing a generator network to predict the optimal, state-dependent guidance scale. Empirical results on text-to-image generation benchmarks show that this method outperforms both heuristic schedules and prior dynamic guidance techniques. AI
