Big Data and Clustering

This chapter is devoted to an introductory discussion on clustering big data. In particular, we briefly reconsider all the most common clustering methods, presented in the previous chapters, and evaluate how they work when the data size increases. The analyses are not based on big data in a strict sense. In fact, the data we investigate do not pose memory/storage problems. Nevertheless, some preliminary relevant conclusions can be drawn even handling “non-small” size data.
