seglearn

Seglearn is a python package for machine learning time series or sequences. It provides an integrated pipeline for segmentation, feature extraction, feature processing, and final estimator. Seglearn provides a flexible approach to multivariate time series and related contextual (meta) data for classification, regression, and forecasting problems. Support and examples are provided for learning time series with classical machine learning and deep learning models. It is compatible with scikit-learn.

Documentation

Installation documentation, API documentation, and examples can be found on the documentation.

Dependencies

seglearn is tested to work under Python 2.7 and Python 3.5. The dependency requirements are based on the last scikit-learn release:

  • scipy(>=0.13.3)
  • numpy(>=1.8.2)
  • scikit-learn(>=0.19.0)

Additionally, to run the examples, you need:

  • matplotlib(>=2.0.0)
  • keras (>=2.1.4) for the neural network examples
  • pandas

In order to run the test cases, you need:

  • pytest

The neural network examples were tested on keras using the tensorflow-gpu backend, which is recommended.

Installation

seglearn-learn is currently available on the PyPi's repository and you can install it via pip:

pip install -U seglearn

or if you use python3:

pip3 install -U seglearn

If you prefer, you can clone it and run the setup.py file. Use the following commands to get a copy from GitHub and install all dependencies:

git clone https://github.com/dmbee/seglearn.git
cd seglearn
pip install .

Or install using pip and GitHub:

pip install -U git+https://github.com/dmbee/seglearn.git

Testing

After installation, you can use pytest to run the test suite from seglearn's root directory:

pytest
