摘要:

我们建立了非平衡最优输运问题熵正则化的数学理论。围绕静态公式展开,依托为非正则化情形构建的形式体系,我们证明非平衡最优输运问题可通过两种性质不同的方式进行正则化——分别在原始空间或扩展空间上实现。我们推导了这两类正则化问题的若干等价表述,特别提出了正则化诱导边缘视角代价函数的概念,借此推导出原始空间正则化的扩展空间公式。我们还证明了扩展空间正则化情形下解收敛到非正则化问题的解,并讨论了基于高阶提升构建统一框架的在研工作,该框架可直接比较两种正则化方法。我们也简要提及这些概念如何转化为对应的动态公式,并给出了应优先采用扩展空间正则化的依据。本文为手稿的初步版本,近期将进行更新。

英文摘要:

We develop a mathematical theory of entropic regularisation of unbalanced optimal transport problems. Focusing on static formulation and relying on the formalism developed for the unregularised case, we show that unbalanced optimal transport problems can be regularised in two qualitatively distinct ways - either on the original space or on the extended space. We derive several reformulations of the two regularised problems and in particular introduce the idea of a regularised induced marginal perspective cost function allowing us to derive an extended space formulation of the original space regularisation. We also prove convergence to the unregularised problem in the case of the extended space regularisation and discuss on-going work on deriving a unified framework based on higher order liftings in which both regularisations can be directly compared. We also briefly touch upon how these concepts translate to the corresponding dynamic formulations and provide evidence why the extended space regularisation should be preferred. This is a preliminary version of the manuscript, to be updated in the near future.
