基于像空间逼近率的变分正则化理论

Variational Regularization Theory Based on Image Space Approximation Rates

Philip Miller

摘要:

我们提出了一种新的方法来收敛速度的结果变分正则化。避免Bregman距离和使用图像空间近似率作为源条件,我们证明了一个近极小极大定理表明,连续模是一个上界的重建误差的常数。应用到Besov空间正则化,我们得到的$0,2,q$ -和$0,p,p$ -罚款没有限制$p,q\in (1,\infty).$的收敛速度的结果最后,我们证明了等价的Hölder型变分源条件,边界上的缺陷的Tikhonov功能,和图像空间逼近率。

英文摘要:

We present a new approach to convergence rate results for variational regularization. Avoiding Bregman distances and using image space approximation rates as source conditions we prove a nearly minimax theorem showing that the modulus of continuity is an upper bound on the reconstruction error up to a constant. Applied to Besov space regularization we obtain convergence rate results for $0,2,q$- and $0,p,p$-penalties without restrictions on $p,q\in (1,\infty).$ Finally we prove equivalence of Hölder-type variational source conditions, bounds on the defect of the Tikhonov functional, and image space approximation rates.
