Gradient Boosting

Hi, I'm doing a Boosting but at the end I notice that I have not had any success. But my dataset has missing values, that affects in the Boosting.

 

Thank,

Re: Gradient Boosting

You can try using a smaller value for the Leaf Fraction property to possibly improve your model.  There are also different options for handling missing values, so try different options for the Missing Values property.  If you have much more than 20K observations in your training data, you can also try increasing the Node Sample property.
