| Introduction
Recent advances in sensor, storage, processing and
communication technologies have enabled the automated recording of data, leading
to fast and continuous flows of information, referred to as data streams.
Examples of data streams are the web logs and web page click streams recorded by
web servers, transactions like credit card usage, data from network monitoring
and sensor networks, video streams such as images from surveillance cameras,
news articles in an RSS reader etc. The dynamic nature of data streams requires
continuous or at least periodic updates of the current knowledge in order to
ensure that it always includes the information content of the latest batch of
data. This is important in applications where the concept of a target class
and/or the data distribution changes over time. This phenomenon is commonly
known as concept drift.
