data ------> knowledge

Are all patterns interesting?

No. only a small fraction of the patterns potentially generated would actually be of interest to a given user.

What makes a pattern interesting?

  • easily understood by humans
  • valid
  • potentially useful
  • novel
  • An interesting pattern represents knowledge.

Can a data mining system generate all of the interesting patterns?

It is often unrealistic and inefficient for data mining systems to generate all possible pattern.
