Symbolic Aggregate approXimation (SAX)

Symbolic Aggregate approXimation

This package implements the Symbolic Aggregate approXimation (SAX) algorithm in C++ with Python bindings using pybind11. SAX is a time series discretization method that represents a continuous-valued time series as a (sliding window of) symbolic representation(s).

Installation

The easiest way to install sax-ts is via pip:

pip install sax-ts

If you want to run the tests locally, install the optional dependencies:

pip install "sax-ts[test]"

You can then import the sax and paa functions as follows:

from sax_ts import sax, paa
