Iterated integral signature calculations

This package provides tools for calculating the signature and log signature of a data stream. These are summary statistics of piecewise linear paths, consisting of iterated integrals, inspired by rough path theory. See <http://www2.warwick.ac.uk/jreizenstein> for more information about the calculations.

It is work in progress.

Python

Install with:

pip install iisignature

For the moment, don’t install this package if you don’t have numpy > 1.7 installed, or if you can’t compile C++ extensions. Log signature calculations (except the slow version) are designed for x86-64 and have only been tested on Linux. They will probably crash on other platforms.
