Constraints in Data Mining

  • Knowledge type constraint:
    • classification, association, etc.
  • Data constraint — using SQL-like queries
    • find product pairs sold together in stores in Chicago this year
  • Dimension/level constraint
    • in relevance to region, price, brand, customer category
  • Rule (or pattern) constraint
    • small sales (price < $10) triggers big sales (sum > $200)
  • Interestingness constraint
    • strong rules: min_support ≥ 3%, min_confidence ≥ 60%
