apriori

What does it mean when apriori min support = 0.05? and how does this differ from min support = 0.5?


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?


Solution

  • 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.
