Mining Data Stream 
Slide: http://www.stanford.edu/class/cs246/slides/16-streams.pdf

Applicable Problems:
  • Estimate the unique elements in continuous data stream
  • Estimation for Big Data
  • finding an ever growing number of applications in networking and traffic monitoring, such as the detection of worm propagation, of network attacks (e.g., by Denial of Service), and of link-based spam on the web
  • an important indication for detecting attacks and monitoring traffic, as it records the number of distinct active flows
