After reading this week’s article, and any other relevant research you locate, please discuss the following in your main post:.
Question 1
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, √ 2×1, √ 2×2, √ 2x1x2, x2 1, x2 2).
Find the maximum margin linear decision boundary in the transformed space.
Question 2
Consider the following set of candidate 3-itemsets: {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 3-itemsets. Assume the tree uses a hash function where all odd-numbered items are hashed to the left child of a node, while the even-numbered items are hashed to the right child. A candidate k-itemset 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 3-itemsets contained in the transaction?
This week’s journal article was focused on the Complexity of Information Systems Research in the Digital World. Complexity is increasing as new technologies are emerging every day. This complexity impacts human experiences. Organizations are turning to digitally enabled solutions to assist with the emergence of digitalization.
Please review the article and define the various technologies that are emerging as noted in the article. Note how these emerging technologies are impacting organizations and what organizations can to do to reduce the burden of digitalization.
Be sure to use the UC Library for scholarly research. Google Scholar is also a great source for research. Please be sure that journal articles are peer-reviewed and are published within the last five years.
The paper should meet the following requirements:
3-5 pages in length (not including title page or references)
APA guidelines must be followed. The paper must include a cover page, an introduction, a body with fully developed content, and a conclusion.
A minimum of five peer-reviewed journal articles.
The writing should be clear and concise. Headings should be used to transition thoughts. Don’t forget that the grade also includes the quality of writing.
Note: This written assignment is a REQUIRED ASSIGNMENT it is worth one-hundred (100) points. You are required to answer the questions as stated in the assignment question in order to obtain credit for the assignment by the due date. If you do not complete the assignment by the due date, you will receive a zero (0) for this assignment. There is a grading criterion associated with this assignment. Your work will be compared to other’s work, using SafeAssign for plagiarism, so please note that copying other people’s responses will not be tolerated.
Prepare a 500 word APA style paper about plagiarism. In the paper be sure to (1) define plagiarism, (2) address why it is unethical, (3) discuss the four different types of plagiarism, and (4) discuss how proper research approaches and documentation styles prevent a student from plagiarizing. Use at least 2 sources in this paper (and please be sure to cite them in the paper). Include an introduction and conclusion and follow the writing guidelines for this course.
The project must be a Word document that is 4pages (double-spaced and APA format) with references must on a cybersecurity topic of your choice.
