Jeremy Reizenstein

I am working on applications of signatures in machine learning with Dr Ben Graham and Dr Anastasia Papavasiliou. In the academic year 2016-2017 I was working at the Alan Turing Institute.

Log signature calculations

  • We have a python package, called iisignature, available on PyPI, which implements signature and log signature calculations reasonably efficiently. User documentation is here. The source code is here. Some simple ideas used in the implementation of the signature parts are explained here.

  • September 2016 presentation is here.

  • Mathematica code for playing with signatures is here.

In 2015-16 and 2016-17 I taught IB9N7/MA936, C++ for Quantitative Finance. Autumn term 2017 too. Details are on my.wbs .
