Features

Incremental Learning

Stream learning models are created incrementally and are updated continuously. They are suitable for big data applications where real-time response is vital.

Adaptive learning

Changes in data distribution harm learning. Adaptive methods are specifically designed to be robust to concept drift changes in dynamic environments.

Resource-wise efficient

Streaming techniques efficiently handle resources such as memory and processing time given the unbounded nature of data streams.

Easy to use

scikit-multiflow is designed for users with any experience level. Experiments are easy to design, setup, and run. Existing methods are easy to modify and extend.

Stream learning tools

In its current state, scikit-multiflow contains data generators, multi-output/multi-target stream learning methods, change detection methods, evaluation methods, and more.

Open source

Distributed under the BSD 3-Clause, scikit-multiflow is developed and maintained by an active, diverse and growing community.

Use cases

The following tasks are supported in scikit-multiflow:

Supervised learning

When working with labeled data. Depending on the target type can be either classification (discrete values) or regression (continuous values)

Single/multi output

Single-output methods predict a single target-label (binary or multi-class) for classification or a single target-value for regression. Multi-output methods simultaneously predict multiple variables given an input.

Concept drift detection

Changes in data distribution can harm learning. Drift detection methods are designed to rise an alarm in the presence of drift and are used alongside learning methods to improve their robustness against this phenomenon in evolving data streams.

Unsupervised learning

When working with unlabeled data. For example, anomaly detection where the goal is the identification of rare events or samples which differ significantly from the majority of the data.


Jupyter Notebooks

In order to display plots from scikit-multiflow within a Jupyter Notebook we need to define the proper mathplotlib backend to use. This is done by including the following magic command at the beginning of the Notebook:

%matplotlib notebook

JupyterLab is the next-generation user interface for Jupyter, currently in beta, it can display interactive plots with some caveats. If you use JupyterLab then the current solution is to use the jupyter-matplotlib extension:

%matplotlib widget
