作者们致力于开发一种直接优化方法,通过奖励模型(如 ImageReward)来改进潜在扩散模型(LDMs)。 通过查看去噪步骤中(作者设置为 40 步)的 ImageReward 评分,作者们得出了一个有趣的见解,直接在步骤t预测x_t \rightarrow x_0^{\prime}时(而不是通过迭代的方式x_t \rightarrow x_{t+1} \rightarrow \ldots ...
摘要本文是 Reward Model 在 Text-to-Image 上的一个应用,训练 RM 模型来判断模型生成的结果如何。本文作者主要对 text-to-image 领域提出了一个 reward model,从而可以对根据 text 生成的 Image 来进行打分。本文主要的贡献在于给出了一个数据集,和将 RM 的想法用在 Text-to-Image 上,是的生成的 Image 更...
这些数据为训练目标ImageReward模型和理解人类审美偏好提供了重要依据。 基于数据本身和注释过程,ImageReward还可以发现文本提示与图像生成的相关问题,理解专家判断的一致性与分歧,为改进模型和未来研究提供重要参考。这也体现了ImageReward在数据获取上的深入考量,不仅注重数量和质量,也力求在数据的基础上获得对任务与人类的...
To begin with, we build ImageReward -- the first general-purpose text-to-image human preference reward model -- to effectively encode human preferences. Its training is based on our systematic annotation pipeline including rating and ranking, which collects 137k expert comparisons to date. In ...
ImageReward model will not be loadeduntil first script run. "Reload UI"will not reload the model nor unload it, butreuses the currently loaded model (if it exists). A"Unload Model"button is provided to manually unload the currently loaded model. ...
ByteEdit seamlessly integrates image reward models dedicated to enhancing aesthetics and image-text alignment, while also introducing a dense, pixel-level reward model tailored to foster coherence in the output. Furthermore, we propose a pioneering adversarial and progressive feedback learning strategy ...
