Researchers have developed a new framework called Reward-Enhanced Scored-Trajectory Distillation (REST) that combines reinforcement learning (RL) with few-step distillation for more efficient text-to-image generation. Unlike previous methods that train these components sequentially, REST co-trains them in a single stage. This approach leverages the reward-scored trajectories generated by RL teachers to supervise a student model, preventing the loss of reward gains during compression. An additional technique, Advantage-Modulated Distillation (AMD), further refines this process by using the advantages of different trajectories to modulate the distillation supervision, strengthening learning from preferred outputs and deterring from less desirable ones. Experiments show REST achieves comparable or superior results to its RL teacher with significantly reduced training costs and faster inference. AI
IMPACT This new distillation technique could lead to more efficient training and faster inference for text-to-image models, potentially lowering the barrier to entry for advanced generative AI applications.
