Stream mining

  • Core assumption is that training examples can be briefly inspected for a single time only.
  • Arrive in a high speed stream and then must be discarded to make room for subsequent examples.
  • Algorithm must update its model incrementally as each element is inspected.
  • It should ideally be able to apply the model any time between training examples.
  • the goal of classification is to produce a model that can predict the class of unlabelled examples by training on examples whose label/class is supplied.
  • Data is assumed to have small and fixed no. of columns or attributes/features. This can be thought of as tuples.
  • The number of examples (rows) are very large and they are assumed to keep arriving in a stream infinitely.
  • The labels that can be applied to the data are limited, typically less than ten.
