Components

The scikit-multiflow is composed of the following sub-packages: * anomaly_detection: anomaly detection methods. * data: data stream methods including methods for batch-to-stream conversion and generators. * drift_detection: methods for concept drift detection. * evaluation: evaluation methods for stream learning. * lazy: methods in which generalisation of the training data is delayed until a query is received, i.e., neighbours-based methods such as kNN. * meta: meta learning (also known as ensemble) methods. * neural_networks: methods based on
