How to find the minimum support in Apriori algorithm

Question

When the percentage values of support and confidence is given how can I find the minimum support in Apriori algorithm. For an example when support and confidence is given as 60%

Answer 1

You have to use the minimum support count to compare the candidate's support count . If you are given the minimum support count as "%" value you have to find the number of transactions first and do the following .

FOR EXAMPLE, you have 10 number of transactions in your Database.

minimum support count is 70%. Now, to get the number as Min. Sup.count = number of transactions * (minimum support count% / 100)

So, min.sup.count= 10 * 70/100

Answer is 7.

This is how you have to calculate min.sup.count
