scikit-learn compatible toolbox for learning with time series/panel data

Project description

travis appveyor pypi gitter binder


A scikit-learn compatible Python toolbox for learning with time series. sktime currently supports:

  • State-of-the-art time series classification and regression algorithms,
  • Classical forecasting including reduction strategies to regression,
  • Benchmarking and post-hoc evaluation methods based on mlaut.

For deep learning methods, we have a separate extension package: sktime-dl.

sktime is under active development and we are looking for contributors. You can find our development roadmap below.


The package is available via PyPI using:

pip install sktime

But note that the package is actively being developed and currently not feature stable.

Development version

To install the development version, please see our advanced installation instructions.


  • Tutorials can be found in the examples folder or can be launched directly on Binder.
  • The full API documentation can be found here.


sktime extends the standard scikit-learn API to handle modular workflows for time series and panel data. The goal is to create a unified interface for various distinct but closely related learning tasks that arise in a temporal data context, such as time series classification or forecasting. To find our more, take a look at our paper.

Currently, the package implements:

  • Various state-of-the-art algorithms for time series classification and regression,
  • Transformers, including series-to-series transforms (e.g. Fourier transform), series-to-primitives transforms a.k.a. feature extractors (e.g. mean, variance), sub-divided into fittables (on table) and row-wise applicates,
  • Pipelining, allowing to chain multiple transformers with a final estimator,
  • Meta-estimators such as reduction strategies, grid-search tuners and ensembles, including ensembles for multivariate time series classification,
  • Composite strategies, such as a fully customisable random forest for time-series classification, with interval segmentation and feature extraction,
  • Classical forecasting algorithms and reduction strategies to solve forecasting tasks with time series regression algorithms.

In addition, sktime includes a high-level API that unifies multiple learning tasks, partially inspired by the APIs of mlr and openML. In particular, we introduce:

  • Task objects that encapsulate meta-data from a dataset and the necessary information about the particular learning task, e.g. the instructions on how to derive the target/labels for classification from the data,
  • Strategy objects that wrap estimators and allow to call fit and predict methods using data and a task object.

Development road map

  1. Development of a time series annotation framework, including segmentation and outlier detection,
  2. Integration of supervised/panel forecasting based on a modified pysf API,
  3. Unsupervised methods including time series clustering,
  4. Design and implementation of a specialised data container for efficient handling of time series/panel data in a modelling workflow and separation of time series meta-data,
  5. Development of a probabilistic modelling framework for time series, including survival and point process models based on an adapted skpro interface.
