Association Rule Learner - Error - Node Created an empty Table

[KavyaMayya]

Hi ,

I’m trying to run the Association rule Learner node and I am getting the message as NODE CREATED AN EMPTY TABLE.

Cell splitter node has got the below table as the output. I am not sure how to fix this issue.

Someone’s assistance on this is much appreciated.

Hi @KavyaMayya and welcome to the forum.

Can you share the configuration of your Association Rule Learner as well? That might shed some light. This particular learner node is very sensitive to parameter adjustments.

Even better would be if you could share your workflow with a small sample dataset included (IF your data isn’t confidential). Workflows almost always work better than screenshots for extensive troubleshooting.

@KavyaMayya most likely you would have to adapt some settings in order to allow lower cover rates (% which your rule must cover). Also you should check how you have set up your workflow.

Here are some examples:

I have tried the few lines but they do not make that much sense and for the Weka nodes I had in mind they do not have the right format. So I used an older example I had from a Kaggle DS. It is just for illustration the values do not make much sense with regards to a sequence. These basic differences Weka HotSpot can deal with strings and numbers and would accept a Target (in your case if you want to differentiate between Errors and Non-Errors). This might potentially handle your duration value…
