新的SpectraReward方法使用MLLMs进行零样本文本到图像生成

作者 PulseAugur 编辑部 · [3 个来源] ·

研究人员推出了一种新颖的、无需训练的奖励函数SpectraReward，旨在利用预训练的多模态大语言模型（MLLMs）作为文本到图像生成的现成奖励模型。该方法评估从生成的图像中重建原始提示的程度，利用MLLM固有的图像-文本对齐能力，而无需偏好标签或奖励模型微调。一个专门的版本Self-SpectraReward，能够在统一的多模态模型中实现闭环自我改进框架。在各种扩散模型、RL算法和MLLM规模上的实验表明，SpectraReward能够持续提高生成性能，优于现有的MLLM衍生奖励训练技术。 AI

影响 这项研究通过实现零样本奖励建模，有望提高文本到图像生成模型的训练效率和有效性。
