A Systematic Literature Review of Novelty Detection in Data Streams: Challenges and Opportunities

Novelty detection in data streams is the task of detecting concepts that were not known prior, in streams of data. Many machine learning algorithms have been proposed to detect these novelties, as well as integrate them. This study provides a systematic literature review of the state of novelty detection in data streams, including its advancement in recent years, its main challenges and solutions, an updated taxonomy for the classification of the proposed frameworks, and a comparative analysis of different key algorithms in this field. Additionally, we highlight ongoing challenges and future research directions that could be tackled moving forward.
