Inverting the signature of a path

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.
