Task1:You need to only answer the a, b, sections of Question 2 which is calculation of support and confidence (similar to what we did in the video)
Submit your answers here as a word or PDF file.
(below is a screen shot from the book)—please check the screenshot to complete this question.
Task2: 4. Investigate via a Web search how models and their solutions are used by the U.S. Department of Homeland
Security in the “war against terrorism.” Also investigate how other governments or government agencies are
using models in their missions.
5.Go to kdnuggets.com. Explore the sections on applications as well as software. Find names of at least three additional packages for data mining and text mining
Table 5.20. Example of market basket transactions.
Customer ID Transaction ID Items Bought
1
0001 {a, d, e}
1
0024 {a,b,c,e}
2
0012 {a,b,d,e}
2
0031 {a, c, d, e}
3
0015 {b, c, e}
3
0022 {b, d, e}
4
0029 {c,d}
4
0040 {a,b,c}
5
0033 {a, d, e}
5
0038 {a,b, e}
(a) Compute the support for itemsets {e}, {b,d}, and {b, d, e} by treating
each transaction ID as a market basket.
(b) Use the results in part (a) to compute the confidence for the associa-
tion rules {b,d} + {e} and {e} + {b,d}. Is confidence a symmetric
measure?
