Meet Parrot: A Novel Multi-Reward Reinforcement Learning RL Framework for Text-to-Image Generation

A pressing issue emerges in text-to-image (T2I) generation using reinforcement learning (RL) with quality rewards. Even though potential enhancement in image quality through reinforcement learning RL has been observed, the aggregation of multiple rewards can lead to over-optimization in certain metrics and degradation in others. Manual determination of optimal weights becomes a challenging task. This…
