Assignment on secure passwords. 

Then pick and three passwords: one not secure, one acceptable, and one very secure. Then write a brief description of the passwords you have chosen, indicating why they are secure or not secure. 

Post between 200 and 300 words. 

1. In CLIQUE, the threshold used to find cluster density remains constant, even as the number of dimensions increases. This is a potential problem since density drops as dimensionality increases; i.e., to find clusters in higher dimensions the threshold has to be set at a level that may well result in the merging of low-dimensional clusters. Comment on whether you feel this is truly a problem and, if so, how you might modify CLIQUE to address this problem.

2. Name at least one situation in which you would not want to use clustering based on SNN similarity or density.

3. 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.

4. We take a sample of adults and measure their heights. If we record the gender of each person, we can calculate the average height and the variance of the height, separately, for men and women. Suppose, however, that this information was not recorded. Would it be possible to still obtain this information? Explain.

5. Explain the difference between likelihood and probability.

6. Traditional K-means has a number of limitations, such as sensitivity to outliers and difficulty in handling clusters of different sizes and densities, or with non-globular shapes. Comment on the ability of fuzzy c-means to handle these situations.

7. Clusters of documents can be summarized by finding the top terms (words) for the documents in the cluster, e.g., by taking the most frequent k terms, where k is a constant, say 10, or by taking all terms that occur more frequently than a specified threshold. Suppose that K-means is used to find clusters of both documents and words for a document data set.

(a) How might a set of term clusters defined by the top terms in a document cluster differ from the word clusters found by clustering the terms with K-means?

(b) How could term clustering be used to define clusters of documents?

8. Suppose we find K clusters using Ward’s method, bisecting K-means, and ordinary K-means. Which of these solutions represents a local or global minimum? Explain.

9. You are given a data set with 100 records and are asked to cluster the data. You use K-means to cluster the data, but for all values of K, 1 ≤ K ≤ 100, the K-means algorithm returns only one non-empty cluster. You then apply an incremental version of K-means, but obtain exactly the same result. How is this possible? How would single link or DBSCAN handle such data?

For Milestone 2 (due in week 5), you will develop an annotated bibliography with a minimum of 10 peer reviewed scholarly articles. Additionally, you will write the literature review for the final project. The entire milestone should be a minimum of 6 pages with 10 peer reviewed scholarly articles.

Your assignment should be 200-300 of your own words.

According to Kirk (2016), The essence of “Formulating Your Brief” is to “identify the context in which your work will be undertaken and then define its aims: it is the who, what, where, when and how.” It could be formal or informal as any project you think you must make it. This phase is where you create a vision for your work.

1. Why is it so important to formulate your brief for a data presentation? Discuss some ways you would implement to formulate an effective brief. What are some advantages to your methods? What are some disadvantages?

2. Please provide a summary as to whether you agree/disagree with their advantages/disadvantages.

Subaru’s Sales Boom Thanks to the Weaker Yen For the Japanese carmaker Subaru, a sharp fall in the value of yen against the U.S. dollar has turned a problem—the lack of U.S. production—into an unexpected sales boom. Subaru, which is a niche player in the global auto industry, has long bucked the trend among its Japanese rivals of establishing significant manufacturing facilities in the North American market. Instead, the company has chosen to concentrate most of its manufacturing in Japan in order to achieve economies of scale at its home plants, exporting its production to the United States. Subaru still makes 80 percent of its vehicles at home, compared with 21 percent for Honda. Back in 2012, this strategy was viewed as something of a liability. In those days, one U.S. dollar bought only 80 Japanese yen. The strong yen meant that Subaru cars were being priced out of the U.S. market. Japanese companies like Honda and Toyota, which had substantial production in the United States, gained business at Subaru’s expense. But from 2012 onward, with Japan mired in recession and consumer prices falling, the country’s central bank repeatedly cut interest rates in an attempt to stimulate the economy. As interest rates fell in Japan, investors moved money out of the country, selling yen and buying the U.S. dollar. They used those dollars to invest in U.S. stocks and bonds where they anticipated a greater return. As a consequence, the price of yen in terms of dollars fell. By December 2015, one dollar bought 120 yen, representing a 50 percent fall in the value of the yen against the U.S. dollar since 2012.    For Subaru, the depreciation in the value of the yen has given it a pricing advantage and driven a sales boom. Demand for Subaru cars in the United States has been so strong that the automaker has been struggling to keep up. The profits of Subaru’s parent company, Fuji Heavy Industries, have surged. In February 2015, Fuji announced that it would earn record operating profits of around ¥410 billion ($3.5 billion) for the financial year ending March 2015. Subaru’s profit margin has increased to 14.4 percent, compared with 5.6 percent for Honda, a company that is heavily dependent on U.S. production. The good times continued in 2015, with Subaru posting record profits in the quarter ending December 31, 2015. Despite its current pricing advantage, Subaru is moving to increase its U.S. production. It plans to expand its sole plant in the United States, in Indiana, by March 2017, with a goal of making 310,000 a year, up from 200,000 currently. When asked why it is doing this, Subaru’s management notes that the yen will not stay weak against the dollar forever, and it is wise to expand local production as a hedge against future increases in the value of the yen. Indeed, when the Bank of Japan decided to set a key interest rate below zero in early February 2016, the yen started to appreciate against the U.S. dollar, presumably on expectations that negative interest rates would finally help stimulate Japan’s sluggish economy. By late March 2016, the yen had appreciated against the dollar and was trading at $1=112 yen.

Questions

 Why do you think that historically, Subaru chose to export production from Japan, rather than set up manufacturing facilities in the United States like its Japanese rivals? 

What are the currency risks associated with Subaru’s export strategy?

 What are the potential benefits?  Why did Subaru’s sales and profits surge in 2014 and 2015? Is Subaru wise to expand its U.S. production capacity?

What other strategies could the company use to hedge against adverse changes in exchange rates? What are the pros and cons of the different hedging strategies Subaru might adopt?
