Freezing Panes & View Options – Challenge activity

1. Follow the instruction given here 
   • Freeze First Column and use the horizontal scroll bar to look at sales from 2015.
   • the first column.
   • Select cell G17 and select Split to split the worksheet into multiple panes. Hint: This should split the worksheet between rows 16 and 17 and columns F and G.
   • Use the horizontal scroll bar in the bottom right of the window to move the worksheet so that Column N, which contains data for January 2015, is next to Column F.
   • Open a new window for your workbook, and select the 2012-2013 Sales
   • Move your windows so they are side by side. Now you’re able to compare data for similar months from several different years.

1. Consider running the Perceptron algorithm on a training set S arranged in a certain order. Now suppose we run it with the same initial weights and on the same training set but in a different order, S 0 . Does Perceptron make the same number of mistakes? Does it end up with the same final weights? If so, prove it. If not, give a counterexample, i.e. an S and S 0 where order matters.

 2. We have mainly focused on squared loss, but there are other interesting losses in machine learning. Consider the following loss function which we denote by φ(z) = max(0, −z). Let S be a training set (x 1 , y1 ), . . . ,(x m, ym) where each x i ∈ R n and y i ∈ {−1, 1}. Consider running stochastic gradient descent (SGD) to find a weight vector w that minimizes 1 m Pm i=1 φ(y i · w T x i ). Explain the explicit relationship between this algorithm and the Perceptron algorithm. Recall that for SGD, the update rule when the i th example is picked at random is wnew = wold − η∇φ  y iw T x i . 

3. Here we will give an illustrative example of a weak learner for a simple concept class. Let the domain be the real line, R, and let C refer to the concept class of “3-piece classifiers”, which are functions of the following form: for θ1 < θ2 and b ∈ {−1, 1}, hθ1,θ2,b(x) is b if x ∈ [θ1, θ2] and −b otherwise. In other words, they take a certain Boolean value inside a certain interval and the opposite value everywhere else. For example, h10,20,1(x) would be +1 on [10, 20], and −1 everywhere else. Let H refer to the simpler class of “decision stumps”, i.e. functions hθ,b such that h(x) is b for all x ≤ θ and −b otherwise. 

(a) Show formally that for any distribution on R (assume finite support, for simplicity; i.e., assume the distribution is bounded within [−B, B] for some large B) and any unknown labeling function c ∈ C that is a 3-piece classifier, there exists a decision stump h ∈ H that has error at most 1/3, i.e. P[h(x) 6= c(x)] ≤ 1/3. (b) Describe a simple, efficient procedure for finding a decision stump that minimizes error with respect to a finite training set of size m. Such a procedure is called an empirical risk minimizer (ERM). 

(c) Give a short intuitive explanation for why we should expect that we can easily pick m sufficiently large that the training error is a good approximation of the true error, i.e. why we can ensure generalization. (Your answer should relate to what we have gained in going from requiring a learner for C to requiring a learner for H.) This lets us conclude that we can weakly learn C using H.

Review the attached file. Suzie has an issue. She can either move to NY or FL and needs to review some data that her agent gave her. The agent reviewed house prices and crime ratings for houses that Suzie would be interested in based on her selection criteria.  She wants to live in an area with lower crime but wants to know a few things:

1. Is it more expensive or less expensive to live in FL or NY?
2. Is the crime rate higher in FL or NY (Note a low score in crime means lower crime)?
3. Is the crime rate higher in lower or higher house price areas?

Using the R tool, show the data in the tool to answer each of the questions.  Also, show the data visualization to go along with the summary.

1. If you were Suzie, where would you move based on the questions above?
2. After you gave Suzie the answer above (to #4), she gave you some additional information that you need to consider:
   1. She has $100,000 to put down for the house.
   2. If she moves to NY she will have a job earning $120,000 per year.
   3. If she moves to FL she will have a job earning $75,000 per year.
   4. She wants to know the following:
      1. On average what location will she be able to pay off her house first based on average housing prices and income she will receive?
      2. Where should she move and why?  Please show graphics and thoroughly explain your answer here based on the new information provided above.

Note: The screenshots should be copied and pasted and must be legible.  Only upload the word document.  Be sure to answer all of the questions above and number the answers.  Be sure to also explain the rational for each answer and also ensure that there are visuals for each question above. Use at least two peer reviewed sources to support your work.

Edition: 3RD 17

 A Usability Evaluation examines the way users interact with products and services in order to achieve a goal. Oftentimes, there are measures that are tied to those goals that are quantified. Academic literature has a robust catalog of research on studies that examine various perspectives that explore user attitudes and experiences. Such attitudes and experiences include:

• System Quality and Usability

Remember, usability is not one-dimensional. It is a complex system of properties. That integrates many factors. It is subjective from user to user. For this assignment, you are asked to explore one of these topics. You are to conduct an analytical research review of the assigned usability category/dimension above. Write a paper that consists of the following:

• Abstract
• Title Page
• Introduction
• Literature Review of Term
• Conclusion

Considerations:

• Must provide a minimum of seven sources that analyze the term and its meaning
• Must analyze and compare the term and how it was evaluated by the authors/scholars in each study
• Must evaluate the study method used to complete the analysis.
• Identify any unique similarities or differences across each study.
• Define your own term based on your understanding of the literature you’ve evaluated.
• Explain how you derive this definition.
• Qualify/quantify the definition by explaining how many sources you used to come up with this definition.
• Make Recommendations of Additional Ideas For Future Literature Review Consideration
• The paper should be a minimum of 10 pages. This does not include the cover page, abstract, or citations. You must use the APA format throughout the entire paper.

IT risk management relies on end-user and administrative compliance with the rules, regulations, and polices set up as a means of protecting information assets within the environment. Comprehension of the consequences and rewards of policy adherence is necessary if security professionals are expected to implement security, and risk management strategies that rely on the strength of policy management and distribution.
