Error Association Rule Learner

[trihanda]

Hi all,
I’m new to both Knime and association rule learning, so please forgive my very beginner question. I’m trying to bring a report sales dataset into knime (attached). It reads perfectly fine but when I try to connect it to the Association Rule Learner I get this error “Node created an empty data table.” :

I literally have done nothing else, so I’m pretty sure there must be some simple setting that I need to change. Or maybe the data pre-processing? Any help would be much appreciated.
My goal is to determine the combination of promotional items based on customer buying behavior.

@trihanda welcome to the KNIME forum. I might take a look at the example later. First you will have to check the settings - most likely you will have to check the data preparation if it is suitable for your data.

Need idea in cluster analysis problem

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…

Then you will have to check the settings of the nodes:

All these nodes have quite some possibilities to configure them; typically some threshold for confidence (reliability of the rule), some minimum coverage (a rule only applying to a small set might be skipped).
