Yes. Each line is a group set.
a.Pleaseimplement analgorithm of your choice (Apriori, or FP-Tree) tofind frequent itemsets. You can importstandardlibraries/modules, but thealgorithm should be written by yourself. Min-support should be a user input parameter. Two sample of transaction datasets, Dataset1and Dataset2, are providedto test if your program works correctly.You can usePython, Java or C++.
b. Extend your program to output all the maximal frequent itemsets and closed frequent itemsets.
c. Extend your program to output all the association rules. Min-Confidence should be a user input parameter. For all the association rules, output measures include support, confidence, lift, all-confidence and cosine.
