Researchers have developed a new reinforcement learning objective called Multi-Axis Max@K to improve the diversity and fairness of text-to-image generation models. This method addresses the issue where current models often produce a limited range of visually distinct outputs for the same prompt, potentially amplifying demographic biases. By assigning credit to samples that contribute to covering different semantic modes, Multi-Axis Max@K enhances the Fairness Score by up to 0.36 relative to base models, while preserving image quality and text alignment.
