• Here we know checking how engine that we tested is less or more than particular threshold value(discussed later, computed by the Gaussian Distribution)
  • fraud detection user example
  • x's = denotes how much user login, typing speed, activity, dll
  • technique used by web to analyzed human behaviour
  • Manufacturing like jet plane example earlier
  • AD on monitoring computers. if one of features is behaving strangely, then there's must be something wrong for the computer
  • Next Gaussian distribution and gaussian algorithm for the tools that used for checking anomaly detection
