Obtaining accuracy of tree-based models

[hechifa39]

In my work, when classifying, I use tree algorithms, but I wanted to obtain the accuracy of the model in the case of training. I did not know where it came from. Please tell me who has an answer

Hi @hechifa39 and welcome back to the KNIME Forum.

If I understand correctly, you want to get these values when using tree algorithms in a classification:

To display these values from the Predictor node, you have to open it and tick the option "Add columns with normalised class distribution ".

I hope this helps.

All the best,

Jose.
