"Cosmetics small xls" data file must be only used for the assignment task one which is association. so assignment is self explanatory, however i am trying to explain it in simple words. PART 1 ,task 1, once association is applied on cosmetics data set , than it will give dozens of rules, however you need to choose the first three rules and interpret.
Explain those rules in your own words. the real art is explaining those rules in words. so please do that properly. for this task please check slide no 35 of the the below attached lecture slide "mining relations"however do read the whole lecture slides as that will be helpful for taks no 1.
Second task is to interpret the 24 rules and talk about the redundant ones and how you interrupt the utilities for these depending upon what you interpret. PART 3 third task is about increasing the confidence from 50 to 75 percent and applying association. after association explain the first few rules and talk about the differences or changes. after 50% and 75 percent .
