Gradient boosting is a useful machine learning technique that uses an ensemble of weak learners to produce high-quality predictions. In this SAS How To Tutorial, Christa Cody presents a high-level introduction to gradient boosting (i.e. no complicated math involved). Then, she builds a machine learning pipeline in SAS Model Studio containing a Gradient Boosting node and explores its options.

Thank you for this! Your explanation about the very basic way in which bagging and boosting works is so wonderful, I did not find this in any other video!

@SASUsers 3 года назад

So glad you enjoyed it, Astha!

Finally, I understood Gradient Boosting.

@SASUsers Год назад

Awesome! Glad you found this tutorial helpful!

Hi Crista, Thank you so much for this video. To understand Gradient Boosting I went through various video but your video gave me proper and required knowledge. You went slow and that helped us to understand in best possible way. Thank you so much and keep posting lecture on ML.

Diana, there are several options for taking your trained models and displaying information about them in a Visual Analytics dashboard. I’ll suggest two of the most likely scenarios. First, you can directly add your model as an object in your dashboard. The advantage of that is as the data updates, the model will update automatically as well. Secondly, you may wish to Derive Predicted values (or probabilities) from the model and then combine those with inputs (effects) in a dashboard. I show you how to do this in the first lesson of our SAS® Visual Statistics in SAS® Viya®: Interactive Model Building course.

Hello Ma'am .... Is there any video on AdaBoost?

@SASUsers 4 года назад

Thank you for your inquiry! We are trying to research this for you!

In this video at time stamp, 5:16, the narrator mentions ADABOOST and how it differs from gradient boosting. We do not have any videos that address ADABOOST specifically. However, this user group paper: 2.sas.com/60501sTDw discusses using ADABOOST.

@chrisb.o.agalaph.d.1916 Год назад

Nicely done. How can I do this with SAS 9 not SAS Viya Model Studio?

@SASUsers Год назад

Great question! Stay tuned, we'll have an answer for you shortly...

@SASUsers Год назад

Behind every node, Model Studio uses procedures to execute the task- you can see this in action in the node’s results where it displays the code for training and scoring. For the Gradient Boosting node, the procedure is ‘proc GRADBOOST’. Here is the documentation for proc GRADBOOST: SAS Help Center: Getting Started: GRADBOOST Procedure 2.sas.com/6054MQKsG

@@SASUsers Thanks so much. This is great!! Will try it out and see how it goes. Will get back!

@SASUsers Год назад

You're very welcome, Chris, and that sounds great - wishing you success!

And then you over train and the kid starts looking into how many definitions of continent there are, and you are back to random answers!
