Data Organization for Data Analysts Assignment 4 Data Mining Concepts Tamer Abdou, PhD April 3, 2017 1. On describing discovered knowledge using association rules One of the major techniques in data mining involves the discovery of association rules. These rules correlate the presence of a set of items with another range of values for another set of variables. The database in this context is regarded as a collection of transactions, each involving a set of items, as shown below. Trans ID Items Purchased 101 milk, bread, eggs 102 milk, juice 103 juice, butter 104 milk, bread, eggs 105 coffee, eggs 106 coffee 107 coffee, juice 108 milk, bread, cookies, eggs 109 cookies, butter 110 milk, bread 1.1 Apply the Apriori algorithm on this dataset. Note that, the set of items is {milk, bread, cookies, eggs, butter, coffee, juice}. You may use 0.2 for the minimum support value. 1.2 Show two rules that have a confidence of 0.7 or greater for an itemset containing three items. 1 2. On describing discovered knowledge using classification Classification is the process of learning a model that describes different classes of data and the classes should be pre-determined. Consider the following set of data records: RID Age City Gender Education Repeat Customer 101 20..30 NY F College YES 102 20..30 SF M Graduate YES 103 31..40 NY F College YES 104 51..60 NY F College NO 105 31..40 LA M High school NO 106 41..50 NY F College YES 107 41..50 NY F Graduate YES 108 20..30 LA M College YES 109 20..30 NY F High school NO 110 20..30 NY F college YES 2.1 Assuming that the class attribute is Repeat Customer, apply a classification algorithm to this dataset. 3. On describing discovered knowledge using clustering Consider the following set of two-dimensional records: RID Dimension 1 Dimension 2 1 8 4 2 5 4 3 2 4 4 2 6 5 2 8 6 8 6 3.1 Use the K-means algorithm to cluster this dataset. You can use a value of 3 for K and can assume that the records with RIDs 1, 3, and 5 are used for the initial cluster centroids (means). 3.2 What is the difference between describing discovered knowledge using
