Scikit-DYN2SEL is a framework for applying and implementing DCS techniques in the data stream mining context.
Scikit-dyn2sel can be easily installed with pip. Just run:
pip install dyn2sel
Scikit-DYN2SEL fully works with ensembles from the scikit-multiflow library, or any implementation that follows the same interface.
Scikit-DYN2SEL classifiers follows the same interface as scikit-multiflow, which is based on the popular scikit-learn. Thus, scikit-DYN2SEL will be extremely familiar if you know any of these libraries.
In its current state, scikit-multiflow contains data generators, multi-output/multi-target stream learning methods, change detection methods, evaluation methods, and more.
Distributed under the MIT license, scikit-DYN2SEL implements the current state of art methods, however if you thinks it that it misses a method, feel free to either open an issue or opening a pull request with your implementation.
The usage of Scikit-DYN2SEL is very straightforward.
