New method fine-tunes generative models using Wasserstein Gradient Flow

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-01 04:00

研究人员开发了一种微调单步生成模型的新方法，该模型将噪声直接映射到数据中，只需一次传递。这种方法被称为通过 Wasserstein Gradient Flow 进行奖励引导的微调（WGF），通过最优传输的视角来查看单步生成器，以实现平滑和可控的分布演变。所提出的训练方法不需要奖励梯度，因此适用于可微分和不可微分的奖励，同时还能缓解奖励破解和模式崩溃等问题。在合成数据、CIFAR-10 和 ImageNet 上的实验表明，与现有方法相比，奖励对齐得到了改善。 AI

影响这种新的微调方法可能导致更高效、更可控的生成模型，并可能影响依赖于图像合成和数据生成的领域。

基于 Wasserstein 梯度流的单步生成模型奖励引导微调

arXiv:2608.29647v1 Announce Type: new Abstract: To mitigate the time complexity of generative models, one-step generative models have recently emerged through direct mapping from noise to data in a single forward pass. However, the reward-guided fine-tuning method of one-step gen…
