Researchers have introduced Curriculum Group Policy Optimization (CGPO), a novel adaptive training framework designed to enhance the efficiency of text-to-image generation models. This method addresses the limitations of uniform sampling by dynamically prioritizing prompts that align with the model's current learning stage. CGPO utilizes the variance in rewards for images generated from a single prompt as an indicator of learnability, increasing the sampling probability for prompts with higher variance. Additionally, a category calibration technique is employed to balance training difficulty across different data categories, leading to improved performance on benchmarks like GenEval and T2I-CompBench++.
