After completion of the week 3 assignment, please briefly describe and explain your recommendations for the manager in the assignment.  What tool or tools did you recommend and why?  In order to receive full credit, you must comment on two other classmates posts.

Chapter #5: 

1. What is an artificial neural network and for what types of problems can it be used? 

2. Compare artificial and biological neural networks. What aspects of biological networks are not mimicked by artificial ones? What aspects are similar? 

3. What are the most common ANN architectures? For what types of problems can they be used? 

4. ANN can be used for both supervised and unsupervised learning. Explain how they learn in a supervised mode and in an unsupervised mode. 

5. Go to Google Scholar (scholar.google.com). Conduct a search to find two papers written in the last five years that compare and contrast multiple machine-learning methods for a given problem domain. Observe commonalities and differences among their findings and prepare a report to summarize your understanding. 

6. Go to neuroshell.com. Look at Gee Whiz examples. Comment on the feasibility of achieving the results claimed by the developers of this neural network model. 

Chapter #6: 

1. What is deep learning? What can deep learning do that traditional machine-learning methods cannot? 

2. List and briefly explain different learning paradigms/ methods in AI. 

3. What is representation learning, and how does it relate to machine learning and deep learning? 

4. List and briefly describe the most commonly used ANN activation functions. 

5. What is MLP, and how does it work? Explain the function of summation and activation weights in MLP-type ANN 

6. Cognitive computing has become a popular term to define and characterize the extent of the ability of machines/ computers to show “intelligent” behavior. Thanks to IBM Watson and its success on Jeopardy!, cognitive computing and cognitive analytics are now part of many real-world intelligent systems. In this exercise, identify at least three application cases where cognitive computing was used to solve complex real-world problems. Summarize your findings in a professionally organized report. 

 Discuss the data visualization in the attached file below (Data Visualization Example) and mention what was right and what did not work? How could you make it better? I want you to respond to at least three other posts to receive points. You can use the attached data file below (Example Data File) to create a better visualization. 

This quiz is based on the material in Chapter 7 of the text. 

Answer each these questions in a paragraph with at least five sentences: Include the question and number your responses accordingly. Provide a citation for each answer.

1. Describe Digital Literacy (how to know what is real on the web). 

2. None of these people exist. What does this mean to you?

3. Why is Wikipedia more reliable than a paper encyclopedia?

4. How useful are crowd sources answers?

5. What are some drawbacks to crowd sourced answers?

6. Do people generally utilize the diversity of sources on the Internet effectively?

7. How reliant are we and how reliant should we be on getting our news from social media?

8. How do humans remain vigilant when we turn over authority to computers? Have you tried to navigate without gps?

9. If models are simplifications or reality, why do we rely on them?

10. Why was this model, used by Amazon for hiring, wrong?

11. Why did Skynet declare war on the human race?

Discussion 1.2

What is so special about GIS? Is GIS art or Science?

Discussion 2.1

What is the difference between GIS and CAD? Why GIS and CAD both exist?

Discussion 2.2

Imagine you are looking at a geodatabase that contains 50 states, 500 cities, and 100 rivers. How many feature classes are there? How many features? How many attribute tables? How many total records in all the attribute tables? 

 1) Name the three essential elements of a basic structured cabling network? How are they installed and what are the components that are involved with them?   (300 words)

Need to 2 Replies discussion for same question for 150 words too.

-Visit MeetMe website and compare it to Facebook. In what ways is it similar to Facebook, and in what ways is it different? Which do you prefer, and why?

-MeetMe- another social network aimed at meeting new people

-2pages worth APA style

-Reference page

Week 15 Discussion

After completing the reading this week, we reflect on a few key concepts this week:

Discuss Howell and Mendez’s three perspectives on follower-ship. Note how these behaviors influence work productivity.

What is the big five personality model?

What is the Myers-Briggs test? How is it similar to the Big five model? How is it different than the Big five model?

Please be sure to answer all the questions above in the initial post.

Please ensure the initial post and two response posts are substantive. Substantive posts will do at least TWO of the following:

Ask an interesting, thoughtful question pertaining to the topic

Expand on the topic, by adding additional thoughtful information

Answer a question posted by another student in detail

Share an applicable personal experience

Provide an outside source

Make an argument

At least one scholarly (peer-reviewed) resource should be used in the initial discussion thread. Please ensure to use information from your readings and other sources from the UC Library. Use APA references and in-text citations.

Operations Security – Risk management policies

Scenario :

“You arrive at work on Monday morning to discover that your computer is not working properly. It stops responding and restarts every few minutes. Unexpectedly, you see unusual error messages popping up and hear some strange sounds from the speakers.”

Discussion Question:

• What is the first possible diagnosis that comes to your mind?
• What is the first step you would take in this situation?
• What is the second step that you would take in this situation?

One and half page is fine

Managing Risk

Your company has decided to implement a human resource demographic portal.  Under the system envisioned, employees would be able to use an online internal web page to change various personal information items themselves, such as, address phone, etc.  In addition, the employees would be able to change limited payroll related items, such as 401k deduction percentages or amounts, optional United Way contributions, and the number of federal and state exemptions to be claimed. Along with thie portal would be the ability to view, download, and print current and YTD pay information, including the current paycheck and check “stub”.  

Under the current system, employees must go to the HR office to make any changes – there is no online access.

Your company already requires direct deposit for all employees, and under the new system, pay stubs would no longer be printed.  Employees would be able to do this as needed through the portal.

 There are many potential risks associated with this project. 

1. Your task is to Identify as many risks as you can (4 is a minimum, but feel free to identify more risks if you so desire).
2. Determine the relative likelihood of each risk occurring (low, medium high)
3. Propose at least one strategy for addressing each risk, and describe the strategy in terms of the 4 risk responses (Avoidance, Transference, Mitigation, or Acceptance).

Remember that sometimes, risks are acceptable and can be taken, so long they are identified and a strategy to address the risk is presented.  For example, driving a car is a risky venture, but to address that risk we have driver’s education (mitigation), manufacturing safety standards (mitigation), insurance (transference), and staying at home (avoidance). Driving an older, unsafe vehicle by an unlicensed and uninsured motorist could be considered acceptance,

Turn in as much as needed. (Sometimes less is more, sometimes more is more; it’s your call.)

Support your strategies as needed with external references, and make sure your answer directly address the potential risks with the  human resource demographic portal.
