Challenge Problems
Push your limits with advanced challenges
Using a dataset of at least 10 transactions, illustrate the Apriori algorithm by calculating the support, confidence, and lift for a small itemset. Present your findings.
💡 Hint: Set up a transaction matrix and systematically work through calculating the support first.
Discuss the trade-offs of using a low support threshold versus a high support threshold in the Apriori algorithm. What are the consequences on the number of rules generated?
💡 Hint: Think about the advantages and disadvantages of finding more data versus potential overfitting on less significant rules.
