Hello KNIME Support team.
I want to check the Scorer of the result predicted by Predictor after learning through H2O AutoML Learner of classification model.
The dependent and predicted variables are String, which node should I use to get the confusion matrix of those values?
The only node given is the H2O Numeric Scorer node, which doesn’t recognize character types.
Is there any way to convert that node to H2O to Table to get the Scorer?
Your answer will be appreciated.
Hi @JaeHwanChoi
You might try (depending on the nature of your results) the H2O Binomial Scorer or the H2O Multinomial Scorer.
You could also convert using H2O to Table and do “regular” scoring, as you suspected.
@JaeHwanChoi H2O will automatically choose a cutoff point and give a result. Depending on your use case (cost of bad classification I either direction) you might want to inspect several options:
