Urgent: Association Rule Learner (Borgelt)

[Prashaant0604]

Hello All,

I need help using the Association Rule Learner (Borgelt).

After using the Group By node to list each transaction and its stock code (concatenate in the group by node).

I am getting an error with the Association Rule Learner (Borgelt) node which states “No transaction column available”.

Group by node:

Error:

Can you please help?

@Prashaant0604 welcome to the KNIME forum.I think you will have to create a list instead of a string:

Association rule for A -> B, but not the other way around

You might want to take a look at this approach: https://www.knime.com/self-tuning-association-rules-for-knime I have integrated this in a collection of Rule Learners (still looking for a good example to demonstrate)

Hello @mlauber71,

I have managed to make it work

The solution was in the node for “Group by”.

It should be in “List” as per below:

Thank you for your help anyways
