Hi everyone! I’m having some issues when using apriori node. When I got my results, instead of give me the real value of the categorical attribute, it returns val1.
For example, there is an attribute with yes and no as values. The result it’s something like this:
do you happen to have a small example workflow you can share with us? Or at least a screenshot of the node configuration and example data?
Which version of KNIME are you using to run your workflow with the Apriori node (Apriori (3.7) – KNIME Hub)?
Kind regards
Marvin
Hi!
Here I share the pictures. All the attributes are categorical, they’re strings. My Knime version is 4.3.4. There you have the node configuration, my data before running weka apriori node and the results. Thank you in advance!
From the description it might well be you have to find and change this setting. Have you checked the options under the ‘more’ button?
B: If used, two characters to use as rule delimiters in the result of toString: the first to delimit fields, the second to delimit items within fields. (default = traditional toString result)
Node details / options
I hope @mlauber71’s suggestion worked for you 
If it did, feel free to mark it as solution, or let us know if it didn’t and we can further look into this.
Kind regards

Sorry, I can’t found where to set B parameter… Even on my Command Line options, the B doesn’t appear! I’m missing something. Can you help me through it? Thanks in advance
Btw, under the “More” button there’s only info, there aren’t any other settings
Sorry, maybe it is a solution, but I don’t know how to apply it. As soon as I solve this, I’ll mark the answer as the solution or share the solution myself. Thanks
