Class,
The final exam will be comprised of these five questions. This is a comprehensive review for all chapters in the textbook. Please address the questions and then submit. You will need to ensure to use proper APA citations with any content that is not your own work. There is no time limit, but make sure to submit by Sunday.
These questions are worth 150 points towards your final grade.
Question 1
Suppose that you are employed as a data mining consultant for an Internet search engine company. Describe how data mining can help the company by giving specific examples of how techniques, such as clustering, classification, association rule mining, and anomaly detection can be applied.
Question 2
Identify at least two advantages and two disadvantages of using color to visually represent information.
Question 3
Consider the XOR problem where there are four training points: (1, 1, −),(1, 0, +),(0, 1, +),(0, 0, −). Transform the data into the following feature space:
Φ = (1, √ 2x1, √ 2x2, √ 2x1x2, x2 1, x2 2).
Find the maximum margin linear decision boundary in the transformed space.
Question 4
Consider the following set of candidate 3itemsets: {1, 2, 3}, {1, 2, 6}, {1, 3, 4}, {2, 3, 4}, {2, 4, 5}, {3, 4, 6}, {4, 5, 6}
Construct a hash tree for the above candidate 3itemsets. Assume the tree uses a hash function where all oddnumbered items are hashed to the left child of a node, while the evennumbered items are hashed to the right child. A candidate kitemset is inserted into the tree by hashing on each successive item in the candidate and then following the appropriate branch of the tree according to the hash value. Once a leaf node is reached, the candidate is inserted based on one of the following conditions:
Condition 1: If the depth of the leaf node is equal to k (the root is assumed to be at depth 0), then the candidate is inserted regardless of the number of itemsets already stored at the node.
Condition 2: If the depth of the leaf node is less than k, then the candidate can be inserted as long as the number of itemsets stored at the node is less than maxsize. Assume maxsize = 2 for this question.
Condition 3: If the depth of the leaf node is less than k and the number of itemsets stored at the node is equal to maxsize, then the leaf node is converted into an internal node. New leaf nodes are created as children of the old leaf node. Candidate itemsets previously stored in the old leaf node are distributed to the children based on their hash values. The new candidate is also hashed to its appropriate leaf node.
How many leaf nodes are there in the candidate hash tree? How many internal nodes are there?
Consider a transaction that contains the following items: {1, 2, 3, 5, 6}. Using the hash tree constructed in part (a), which leaf nodes will be checked against the transaction? What are the candidate 3itemsets contained in the transaction?
Question 5
Consider a group of documents that has been selected from a much larger set of diverse documents so that the selected documents are as dissimilar from one another as possible. If we consider documents that are not highly related (connected, similar) to one another as being anomalous, then all of the documents that we have selected might be classified as anomalies. Is it possible for a data set to consist only of anomalous objects or is this an abuse of the terminology?
