Abstract: With the continuous advancement of scientific and technological development, static data classification technology can not meet the real needs of the situation. Large amounts of data are based on data stream, this paper summarizes the new form of data classification algorithms. The main algorithms which being described are ensemble classification, ANNCAD and VFDT. Through the study of research and experimental comparison of the results, people can find these data streams on classification algorithms performance far exceeds the traditional classification algorithms.

Key words: data stream, classification, concept drift
