具有任意维超光滑误差的Wasserstein反褶积的极小极大收敛速度

Minimax rates of convergence for Wasserstein deconvolution with supersmooth errors in any dimension

Jérôme Dedecker, Bertrand Michel

摘要:

本文的主题是估计的概率测度${\mathbb R}^d$从观测数据与一个加性噪声下,Wasserstein度量的顺序$p$(与$p\geq 1$)。我们假设误差的分布是已知的,并且属于一类超光滑分布,并且我们给出了$p$阶Wasserstein度量的最优收敛速度。特别是,我们展示了如何使用现有的下限的累积分布函数的估计在维度1找到下界的Wasserstein反卷积在任何维度。

英文摘要:

The subject of this paper is the estimation of a probability measure on ${\mathbb R}^d$ from data observed with an additive noise, under the Wasserstein metric of order $p$ (with $p\geq 1$). We assume that the distribution of the errors is known and belongs to a class of supersmooth distributions, and we give optimal rates of convergence for the Wasserstein metric of order $p$. In particular, we show how to use the existing lower bounds for the estimation of the cumulative distribution function in dimension one to find lower bounds for the Wasserstein deconvolution in any dimension.
