Association Rule Table return empty


I have tried various combinations as well as change the values of the confidence and support level but the table still returns 0. I have successfully generated associated rules with R for this dataset.

Did I do something wrong somewhere?

Hi @Archangel!

The problem is that when you concatenate your items using groupby, you transform them to a single string instead of multiple strings together. Try to change your aggregation method in the groupBy node to “list”. This will already output a collection-type cell and you can use it directly with your association rule learner.

Please let me know if this helps!



Thank you very much, Ana. It works like a charm.
