新Rao-Blackwellized分数匹配方法用于流形数据

研究人员开发了一种名为Rao-Blackwellized分数匹配(DSM)的新方法,以解决数据位于流形上的统计建模挑战。该技术通过条件化投影来优化去噪目标,有效消除了由环境高斯噪声引起的奇异性。所得方法提供了$L^2$-最优预测器,并深入了解了数据分布的内在和外在几何特性。 AI

影响 引入了一种用于流形数据建模的新型统计技术,可能改进生成模型和表示学习。

    We study denoising score matching (DSM) when the latent distribution is supported on a smooth embedded manifold $M \subset \mathbb{R}^D$. Under ambient Gaussian corruption, the tangent denoising target contains a singular normal-fiber noise channel whose variance diverges as $d/σ…
