association rule mining problem/ absolute number or percentage

Hi I wonder whether someone can tell me what is the difference between absolute number and percentage in association rule mining item set setting section.
It seems that if i don’t choose to use absolute number, I will run into errors: node created an empty data table.

Thanks in advance!

If anyone know where I can help detailed explanations of these parameters on Knime, let me know. Thanks

Here’s an older post from our site on the Association Rule Learner (Borgelt) node that you may find helpful:

The absolute number / percentage option applies to the minimum support, which itself is described in more detail in the above article. Hope that helps!
