Hi there,

I have trained a “gradient boosted tree model” to my dataset, which works surprisingly really good. Now I would like to analyse the model to find out, which data input (my model uses 24 input columns, one target column) has the biggest influence on the result.  
Is there a node to do such a sensitivity analysis available? How do you check your models?

Andreas

Hello @ActionAndi -

The standard Gradient Boosted Trees Learner node currently doesn’t provide a measure of variable importance. The H2O Gradient Boosting Machine Learner, however, does!

Check out this workflow:

Hi Scott,

Wow, that is exactly the node I was looking for!
