Case study in stream learning

The case study in this chapter consists of several experiments that illustrate different methods of stream-based machine learning. A well-studied dataset was chosen as the stream data source and supervised tree based methods such as Naïve Bayes, Hoeffding Tree, as well as ensemble methods, were used. Among unsupervised methods, clustering algorithms used include k-Means, DBSCAN, CluStream, and CluTree. Outlier detection techniques include MCOD and SimpleCOD, among others. We also show results from classification experiments that demonstrate handling concept drift. The ADWIN algorithm for calculating statistics in a sliding window, as described earlier in this chapter, is employed in several algorithms used in the ...
