(c) Display a bar chart showing the response frequencies and their percentages of the total responses. Grading Rubric – 10 points for defining functions. – 15 points for finishing Task1(a)-(c). – 5 points for appropriate comments. – 10 points for a runnable python program with correct data visualization. – 10 points for screenshots of the program. Task 2 (50 points): (Classification with k-Nearest Neighbors and the Digits Dataset) Read the file “09-02-MachineLearning.pdf” and the python program “CaseStudy1.py” to learn the algorithm of k-Nearest Neighbors with the Digits dataset for recognizing handwritten digits. Re-write the python program by doing the following subtasks: (a) Write code to display the two-dimensional array representing the sample image at index 24 and numeric value of the digit the image represents. (b) Write code to display the image for the sample image at index 24 of the Digits dataset. (c) For the Digits dataset, what numbers of samples would the following statement reserve for training and testing purposes? X train, X test, y train, y test = 1 train test split(digits.data, digits.target, random state=11, test size=0.60) 2 (d) Write code to get and display these numbers. (e) Rewrite the list comprehension in snippet [50] using a for loop. Hint: create an empty list and then use the built-in function “append”. Grading Rubric – 15 points for finishing Task2(a)-(e). – 5 points for appropriate comments. – 20 points for a runnable rewritten python program – 10 points for screenshots of the program. 

Kirk (2019) notes the importance of formulating your brief.  What does he mean by this?  Please expand this thought by noting how you would create a vision for your work.  Note any real-world examples to expand upon this thought.

 

Excel worksheets contain a set of receipt data for a bakery where each row represents a different customer’s purchase. For each row, a 1 indicates they purchased that product and a 0 means they did not. In total, there are 50 different products the bakery sells, and the owner is interested in determining any association rules in the purchase patterns of their customers.

Complete an Association Rule analysis on the following data using a minimum confidence percentage of 70% and a minimum support of 10.

 Answer the following questions:

1. How many rules did Association Rule analysis found?
2. Pick any one of the resultant rules developed by your analysis and explain each of the columns in the output using that rule as an example.
3. Select the 5 rules you would recommend to the bakery owner and explain your reasoning.

Please upload the completed workbook which shows your association rule analysis and answers to the questions.
