Hello everyone, I hope you all doing well. I gave both the apriori and fpgrowth functions a list of item sets that are from size 2 and larger, but the functions output itemsets start from size 1 not 2. Isn't this wrong for both algorithms? |

Itemsets can usually have any size from 1 to the number of possible items. You can set a higher support value to avoid the small itemsets. |
