Negative and Rare Patterns

  • Rare patterns: Very low support but interesting
    • E.g., buying Rolex watches
    • Mining: Setting individual-based or special group-based support threshold for valuable items
  • Negative patterns
    • Since it is unlikely that one buys Ford Expedition (an SUV car) and Toyota Prius (a hybrid car) together, Ford Expedition and Toyota Prius are likely negatively correlated patterns
  • Negatively correlated patterns that are infrequent tend to be more interesting than those that are frequent
