A Novel Multi-Reward Reinforcement Learning RL Framework for Text-to-Image Generation
Introduction
A pressing issue arises in text-to-image (T2I) generation using reinforcement learning (RL) with quality rewards. The aggregation of multiple rewards can lead to over-optimization in certain metrics and degradation in others, creating a need for an effective strategy that jointly optimizes multiple rewards in RL for T2I generation.
Practical Solutions and Value
Parrot, a novel multi-reward RL framework, addresses the challenges in T2I generation by employing a joint optimization approach for the T2I model and prompt expansion network. It introduces original prompt-centered guidance at inference time to counteract potential forgetting of the original prompt. The framework improves multiple quality metrics, such as aesthetics, image sentiment, and human preference, and effectively captures the original prompt while incorporating visually pleasing details.
Adaptability and Ethical Considerations
Parrot’s adaptability to a broader range of rewards enhances its applicability in quantifying image quality. However, ethical concerns arise regarding its potential to generate inappropriate content, emphasizing the need for scrutiny and ethical considerations in deployment.
