Tree-Based Machine Learning Methods and Model Interpretability in SAS® Viya®: A Case Study

On-Demand • Cost: Complimentary

About the webinar

Join this webinar to learn how to build machine learning pipelines in SAS Viya.

We will go into detail on key machine learning topics like data preprocessing, variable selection, building tree-based models and model interpretability.

This webinar is perfect for new or experienced SAS users who want to learn more about machine learning. You will learn how to build more complex predictive models (above and beyond linear models).

You will learn:

  • How to use SAS Model Studio to build machine learning pipelines to improve your predictive modeling workflow.
  • How nonlinear models, such as tree-based models, can improve model accuracy as compared to traditional linear models.
  • How to add interpretability plots to black box models and how to use these plots to understand and improve predictive models.
