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).
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:
