Proposal of a new stability concept to detect changes in unsupervised data streams

作者:

Highlights:

• We propose a new stability concept for unsupervised data streams.

• The concept is based on ideas from time series analysis.

• A stable algorithm is introduced for change detection in unsupervised streams.

• Experiments provide insights on how the stability concept work in several scenarios.

• Results show our change detection algorithm correctly detects changes on a stream.
