I used python for apriori but I was confused seeing min support = 0.05 in many models. Doesn't this mean min support is only 5% and how can this be relied on when discovering the existing patterns in the data?
0.05 refers to 5%, which means the fraction of transactions with probability of item 'A' and 'B' occurring together as compared to the total number of transactions is 5 out of 100.
