度量空间中的邻近点法

The proximal point algorithm in metric spaces

Miroslav Bacak

摘要:

邻近点法是一种著名的求凸函数极小值的方法,本文将其从经典的希尔伯特空间推广到非线性的非正曲率测地线度量空间.我们证明了由邻近点法产生的序列弱收敛于极小点,并讨论了一个相关的问题:梯度流的收敛性。

英文摘要:

The proximal point algorithm, which is a well-known tool for finding minima of convex functions, is generalized from the classical Hilbert space framework into a nonlinear setting, namely, geodesic metric spaces of nonpositive curvature. We prove that the sequence generated by the proximal point algorithm weakly converges to a minimizer, and also discuss a related question: convergence of the gradient flow.
