I am completely new to KNIME and have been trying to run some examples.
More specifically I tried to use the Decision tree for the "Iris" dataset and although I think I followed all the right steps in the end I get 0 accuracy. The same happens when I try Naive Bayes with another dataset. I know this sounds too vague, but I have no idea what I could be doing wrong. Could anyone help?
Thanks in advance.
