In this assignment you will be exploring the features of Splunk. For this assignment you will be sharing a Word document  or PDF with Screen Shots of each step. Please make sure the screenshot is in a resolution which makes it readable. 
To complete this assignment first you will
Make sure you install splunk following the instructions shared with you in the lecture and are able to run it. Screenshot should show your browser window with splunk open in it. (1 points)
Load the attached CSV Download attached CSVfile in Splunk. The dataset is related to crimes reported in Atlanta between 2009-2017. Source of data is https://data.world/bryantahb/crime-in-atlanta-2009-2017Links to an external site. 
I went over how to load CSV file in Splunk in the lecture videos. Screenshot should show the dataset loaded in your browser window (1 points)
3. Query for all “AUTO THEFT” and take a screenshot of the query and results for the query.  You don’t have to show all the results. Just enough to make   sure you are able to run the query(2 points)
4. Query for all “AUTO THEFT” which occurred between 1st of January of 2011 (Inclusive) and 31st December 2013 (Inclusive)  take a screenshot of the query and results for the query.  You don’t have to show all the results. Just enough to make sure you are able to run the query (4 points)
5. Create a pie chart of various types of crimes e.g. Auto Theft, AGG ASSAULT etc. The Screenshot should show the pie chart. (4 points)
6. Query the data to show type of crime and the frequency and sort it by the most common type of crime to least common type of crime.Screenshot should show the query along with the results.  (8 points). 
7. Create a bar chart to show on X axis – neighborhood and Y-axis the frequency of crimes in the neighborhood (10 points)

The PHP language is linked to a database to retrieve user information such as their details and addresses

1. Why are IEEE FP numbers not the same as real numbers – or even rational numbers? Why are “Integer” numbers on a computer not the same as the Integer numbers in Mathematics?  Your answer must include Mathematical definitions of the Integers and the Reals, and also the computer definitions of Integers and Floating Point numbers.
2. What is out-of-order execution? How is it related to pre-fetching instructions? Give an example of where it occurs. Your answer must include a discussion about how and why we predict a branch, and why we may partially unroll loops.
3. Why do CPUs typically require more power than domain specific processors (DSA)? What percentage of ISA design do you think is affected by the power issue, and what percent is determined by the need to focus on RISC architecture?
4. Assume you have a new processor in front of you and you want to know how large to construct your input set. What type of a graph can you draw to help you decide when you are weakly scaling the built-in parallelism in your system, and when you have reached Amdahl’s law limits?  Describe the axis of this graph, and the part on the graph that tells you you’ve reached Amdahl’s law limits.

Decision Tree (25 points)
Description:
In this weeks assignment you will be exploring Decision Tree algorithm from Scikit learn on your own using a different dataset. You will be doing the following tasks
Download the Jupyter notebook which was shared with you in Canvas and I went over in the lecture
Read the description for Wine dataset which is included in the Scikit-learn library (Similar to Iris)
https://scikit-learn.org/stable/modules/generated/sklearn.datasets.load_wine.html#sklearn.datasets.load_wineLinks to an external site.
If you check this page towards the end you will see sample code about how to load the wine dataset in the same fashion as Iris was loaded
3. Read the description for Decision Tree on scikit-learn’s website
https://scikit-learn.org/stable/modules/tree.htmlLinks to an external site.
and how the tree can be exported using GraphViz https://graphviz.readthedocs.io/en/stable/manual.htmlLinks to an external site.
4. Modify the Jupyter Notebook which was shared with you to achieve the following goals
Load the wine dataset in place of Iris dataset (5 points)
Use the code to do classification on the wine dataset similar to Iris (5 points)
Identify the accuracy numbers.
Check the documentation for Decision Tree on https://scikit-learn.org/stable/modules/generated/sklearn.tree.DecisionTreeClassifier.html#sklearn.tree.DecisionTreeClassifierLinks to an external site. and notice the parameter min_samples_split
Tweak the value of min_samples_split with three different values. You can decide the values, but for each alteration to min_samples_split you have to print the accuracy numbers.  (10 points)
Export the decision tree image for the value of min_samples_split which gives the highest accuracy using graphviz library as described in previous bullet point (3) as a PDF file “wine.pdf”   (5 points) 
What to submit:
Create a zip file containing 
Your Jupyternotebook with the code changes. 
PDF file with your decision tree.

The discussion assignment provides a forum for discussing relevant topics for this week on the basis of the course competencies covered.
For this assignment, make sure you post your initial response to the Discussion Area by the due date assigned.
To support your work, use your course and text readings and also use the South University Online Library. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates’ initial postings. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Cite sources in your responses to other classmates. Complete your participation for this assignment by the end of the week.
Tasks
Hidden implementations are often said to exist in a black box. What are the advantages of this approach in both programming and real life? Are there any disadvantages?
A program subdivided into methods allows different programmers to write separate methods, thus dividing the work. Would you prefer to write a large program by yourself or to work on a team in which each programmer produces one or more modules? Why?

Avoid plagiarism, the work should be in your own words, copying from students or other resources without proper referencing will result in ZERO marks. No exceptions. All answered must be typed using Times New Roman (size 12, double-spaced) font. No pictures containing text will be accepted and will be considered plagiarism).

Introduction
The global economy went through a difficult period due to COVID-19. Many businesses did struggle, and some unfortunately failed. While COVID-19 brought immense challenges, it also opened doors for new business and innovative opportunities.
Peloton’s Rise and Fall
Peloton, the high-end at-home fitness company, initially thrived during the early stages of the pandemic. With gyms closed and people stuck at home, demand for their stationary bikes and fitness classes skyrocketed. However, by 2022, they faced significant challenges. They overestimated demand and built-up excess inventory, leading to stockpiling and financial losses. Competitors like NordicTrack and Echelon offered cheaper alternatives, chipping away at Peloton’s market share. Rising inflation and interest rates squeezed consumer spending, making luxury items like Peloton bikes less affordable. Peloton cut expenses, closed stores, and laid off employees to streamline operations. They launched lower-priced bikes and accessories to broaden their customer base. They invested heavily in their app and content offerings, enhancing the virtual fitness experience. Collaborations with retailers like Dick’s Sporting Goods and Amazon expanded their reach. They focused on building community and the emotional benefits of fitness rather than just pushing product sales. While the road was bumpy, Peloton’s efforts are starting to pay off. They’ve reduced their losses, streamlined operations, and are seeing signs of renewed customer demand. The company has shown resilience and adaptability in the face of adversity.
Note: The above-mentioned case study is just an example; students are supposed to find a case study of business that faced significant challenges during the pandemic but found innovative ways to overcome them.
