本文的目的是开发一个显式的过程,使人们能够从其签名中重建任何C^1路径(自然参数化)。我们还明确量化重建的路径和原始路径之间的距离,在签名中的条款,用于建设和模的连续性的衍生物的路径。在建设中的一个关键成分是使用的对称化,分离的行为的路径在小尺度和大尺度的程序。
The aim of this article is to develop an explicit procedure that enables one to reconstruct any $C^1$ path (at natural parametrization) from its signature. We also explicitly quantify the distance between the reconstructed path and the original path in terms of the number of terms in the signature that are used for the construction and the modulus of continuity of the derivative of the path. A key ingredient in the construction is the use of a procedure of symmetrization that separates the behavior of the path at small and large scales.
