Association Analysis Algorithms

Association Analysis Algorithms

Apriori Algorithm

• Finds frequent itemsets using a "bottom-up" approach
• Eliminates infrequent combinations early

• More efficient than Apriori
• Uses a tree structure (FP-tree) to find frequent itemsets without candidate generation
