变分正则化反问题与机器学习

Variational Regularization in Inverse Problems and Machine Learning

Friedrich-Alexander Universität Erlangen-Nürnberg(埃尔朗根-纽伦堡大学)

摘要:

本文讨论了变分正则化方法的基本结果和最近的发展,为反问题。在一个典型的设置中,我们回顾了获得收敛正则化方案所需的基本性质,并进一步讨论了定量估计的推导,分别需要的成分,如Bregman距离凸泛函。除了为逆问题开发的方法外,我们还将讨论机器学习中的变分正则化,并与经典正则化理论建立一些联系。特别是,我们将讨论重新解释的机器学习问题的正则化理论的框架和重新解释的变分方法的反问题的框架中的风险最小化。此外,我们建立了一些以前未知的Bregman距离的误差估计和泛化误差之间的连接。

英文摘要:

This paper discusses basic results and recent developments on variational regularization methods, as developed for inverse problems. In a typical setup we review basic properties needed to obtain a convergent regularization scheme and further discuss the derivation of quantitative estimates respectively needed ingredients such as Bregman distances for convex functionals. In addition to the approach developed for inverse problems we will also discuss variational regularization in machine learning and work out some connections to the classical regularization theory. In particular we will discuss a reinterpretation of machine learning problems in the framework of regularization theory and a reinterpretation of variational methods for inverse problems in the framework of risk minimization. Moreover, we establish some previously unknown connections between error estimates in Bregman distances and generalization errors.
