Major Pattern Discovery Tasks: Association and Sequential Patterns

Introduce two central pattern mining tasks by studying frequent itemsets, support, confidence, confidence-based pruning, and the role of constraints such as window size and maxgap in sequential pattern discovery.

Lesson explanation

Pattern mining searches data for recurring relationships. Association analysis identifies frequent itemsets and rules; sequential pattern mining considers order and time.Association measuresSupport measures how often an itemset occurs.Confidence measures how o...
