pecuzal-embedding 1.0.3

PECUZAL automatic embedding of uni- and multivariate time series

PECUZAL Python

We introduce the PECUZAL automatic embedding of time series method for Python. It is solely based on the paper [kraemer2020] (Open Source), where the functionality is explained in detail. Here we give an introduction to its easy usage in three examples. Enjoy Embedding!

Getting started

Install from PyPI by simply typing

pip install pecuzal-embedding

in your console.

NOTE

This implementation is not profiled well. We recommend to use the implementation in the Julia language or in Matlab, in order to get fast results, especially in the multivariate case. Moreover, it is well documented and embedded in the DynamicalSystems.jl ecosystem. For instance, the compuations made in the sec_univariate and the sec_multivariate in this documentation took approximately 500s and 1680s, respectively. In the Julia implementation the exact same computation took 3s and 20s, respectively! (running on a 2.8GHz Quad-Core i7, 16GB 1600 MHz DDR3)

Documentation

There is a documentation available including some basic usage examples.
