Abstract

Drift detection methods in data streams can detect changes in incoming data so that learned models can be used to represent the underlying population. In many real-world scenarios context information is available and could be exploited to improve existing approaches, by detecting or even anticipating to recurring concepts in the underlying population. Several applications, among them health-care or recommender systems, lend themselves to use such information as data from sensors is available but is not being used. Nevertheless, new challenges arise when integrating context with drift detection methods. Modeling and comparing context information, representing the context-concepts history and storing previously learned concepts for reuse are some of the critical problems. In this work, we propose the Context-aware Learning from Data Streams (CALDS) system to improve existing drift detection methods by exploiting available context information. Our enhancement is seamless: we use the association between context information and learned concepts to improve detection and adaptation to drift when concepts reappear. We present and discuss our preliminary experimental results with synthetic and real datasets.
