Advances in Gradient Boosting: the Power of Post-Processing

Learn how TreeNet stochastic gradient boosting can be improved by post processing techniques such as GPS Generalized Path Seeker, RuleLearner, and ISLE.

Course Outline:

I. Gradient Boosting and Post-Processing:

  • What is missing from Gradient Boosting?
  • Why post-processing techniques are used?

II. Applications Benefiting from Post-Processing: Examples from a variety of industries.

  • Financial Services
  • Biomedical
  • Environmental
  • Manufacturing
  • Adserving

III. Typical Post-Processing Steps

 

IV. Techniques

  • Generalized Path Seeker (GPS): Modern high-speed LASSO-style regularized regression
  • Importance Sampled Learning Ensembles (ISLE): identify and reweight the most influential trees
  • RuleLearner: ISLE on “steroids.” Identify the most influential nodes and rules

V. Case Study Example

  • Output/Results without Post-Processing
  • Output/Results with Post-Processing
  • Demo
