新的 Energy-Tweedie 恒等式连接去噪与分数估计

研究人员引入了 Energy-Tweedie 恒等式,它将去噪与分数估计之间的关系从高斯噪声扩展到更广泛的吉布斯(基于能量)噪声分布。这一新恒等式建立了吉布斯噪声、后验定律和核分数规则之间的分布对应关系。研究结果提供了一种估计未知噪声参数的方法,并能够沿着用户定义的路径进行扩散式采样,从而为使用分数规则训练的近期生成模型提供了基于分数的视角。 AI

影响 扩展了去噪和分数估计的理论理解,可能影响未来的生成模型开发。

    Energy-Tweedie: Score meets Score, Energy meets Energy

    arXiv:2512.23818v2 Announce Type: replace Abstract: Denoising and score estimation are classically linked through Tweedie's formula, which relates the posterior mean under Gaussian noise to the Stein score of the noisy marginal. In this work, we extend this perspective beyond Gau…
