Tune Gradient Boosting Node

For my dataset, I run Regression, Neural Network,  Decision Trees & Gradient Boosting Nodes. GB node always has the highest MSE, even higher than Regression. Even after I changed N interations to 200, it is still the worst one. Could you suggest what other parameters I can try out to improve the outcome? I run my dataset on R & Python, GB from both give very good results. Don't know what is wrong with SAS's GB node. My problem is of regression, not of classification.

One thing to try would be using a smaller value for Leaf Fraction - could be too high to find splits.

Re: Tune Gradient Boosting Node

May I know what is leaf fraction and why we need to use a smaller for it?
