Abstract:
Data stream mining is a natural and necessary progression from traditional data mining. However, it presents additional challenges to batch analysis: along with strict time and memory constraints, change is a major consideration. In a dynamic data stream the underlying concepts may drift and change over time. The challenge of recognizing and reacting to change in a stream is compounded by the scarcity of labels problem. This talk presents our recent work to evaluate unsupervised learning as the basis for online classification in dynamic data streams with a scarcity of labels. A novel stream clustering algorithm based on the collective behaviour of ants, called Ant Colony Stream Clustering (ACSC), is present. Furthermore, a novel framework, Clustering and One class Classification Ensemble Learning (COCEL), for classification in dynamic streams with a scarcity of labels is described. The proposed framework can identify and react to change in a stream and hugely reduces the number of required labels (typically less than 0.05% of the entire stream). Finally, some conclusions will be made.
