Answer the following questions. Please ensure to use the Author, YYYY APA citations with any content brought into the assignment.  

For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not be desirable?

Describe the change in the time complexity of K-means as the number of clusters to be found increases.

Discuss the advantages and disadvantages of treating clustering as an optimization problem. Among other factors, consider efficiency, non-determinism, and whether an optimization-based approach captures all types of clusterings that are of interest.

What is the time and space complexity of fuzzy c-means? Of SOM? How do these complexities compare to those of K-means?

Explain the difference between likelihood and probability.

Give an example of a set of clusters in which merging based on the closeness of clusters leads to a more natural set of clusters than merging based on the strength of connection (interconnectedness) of clusters.

DISCUSSION

 

What’s simple random sampling? Is it possible to sample data  instances using a distribution different from the uniform distribution?  If so, give an example of a probability distribution of the data  instances that is different from uniform (i.e., equal probability).

All discussions should contain at least one reference (and matching in-text citation in APA format).

Instructions

You have been recently promoted to IT manager and have been asked to analyze the current software and storage. Then you will need to present to the CIO the various software available as described below. You will also need to present to the CIO information about the progression of storage devices, new developments in storage devices, and how productivity is related to storage devices, along with how storage devices impact users.

Part 1

Read the following brief descriptions of software. Write 1–2 pages identifying the software by name, a detailed definition, and description.

Copyrighted software that is distributed at no cost for a trial period. After the trial period, the user is billed automatically.

Software provided for use, modification, and redistribution. There are no restrictions from the copyright holder. It is usually downloaded at no cost. The draw is that users can share improvements and personalize the software to meet their needs.

This software is an application that enables designers to create high-quality professional publications with text and graphics. Business users might use it for annual reports, marketing, and newsletters. Personal users might produce flyers, calendars, and business papers.

This technology uses radio signals to transmit with a tag in or attached to an object, animal, or even person. They are often used in retail, inventory, tickets, or to access monitored environments.

This code stores information in a vertical and horizontal direction. It stores information that requires a reader for interpretation that interacts with a Web site.

Part 2

Using research from the resources, the Capella Library, or the Internet, write 1–2 pages in which you describe the chronological progression of storage devices. Include:

Instances that spurred new development.

The effect on productivity and storage practices.

The impact on users in a professional environment.

Additional Requirements

Written communication: Written communication is free of errors that detract from the overall message. Use spell check in Word to confirm spelling and grammar.

Format: Follow current APA formatting guidelines.

Font and font size: Use Times New Roman, 12 point.

Length of paper: 1–2 pages per part, double-spaced.

Assignment

  

1.[13]  The oral arguments before the Supreme Court concerning the Communications Decency Act (CDA) focused extensively on determining the most appropriate analogy for cyberspace.  Arguments were presented that compared the Internet to a library, to television, and to a public place such as a street corner or park.

(a)   Why are these comparisons important?  Briefly explain the differences between libraries, television, and public places with respect to First Amendment protection.

 (b)   For each of these three analogies (library, television, and public place), describe one significant way in which the Internet is similar and one significant way in which it is different.  Explain the relevance of each of these similarities and differences to the issue of regulation of the Internet.

2.[12]   Veterinarians implant computer chips into pets and farm animals to identify them if they get lost. Some people suggest doing so for children. Discuss the privacy implications of this proposal and answer the following questions:

a. What are the risks?

b. Do the benefits outweigh the risks? If yes, in what way? If not, why not?

c. Do parents have the right to have the chips implanted in their young children?  Why or why not?

                d. If there was a bill in Congress to require ID chips in children under the age of 5, would you support it? Why or why not?

3. [10] a. Two approaches to the problem of protecting personal information are (a) the free market view and (b) the consumer protection view.  How do these points of view differ on the issue of a company disclosing personal information about its customers?  How do they differ on the issue of errors in the data about an individual that is distributed by a credit bureau?

        b. Briefly describe what an “opt-in” policy is and an “opt-out” policy is. Let’s say you were filling out a survey for an online magazine.  Give an example of what you’d see that would distinguish an opt-in from an opt-out policy.

4. [15]  a. Briefly describe the difference between negative and positive rights (liberties and claim rights). Give an example of a negative right and a positive right.

     b. Explain the DMCA (Digital Millennium Copyright Act). What are its two main provisions? 

c. How are the Napster and Grokster copyright cases similar, and how are they different?

d. Explain the difference between deontological theories of ethics and utilitarian theories of ethics
