I. Gradient Boosting and Post-Processing:
o What is missing from Gradient Boosting?
o Why post-processing techniques are used?
II. Applications Benefiting from Post-Processing: Examples from a variety of industries.
o Financial Services
III. Typical Post-Processing Steps
o Generalized Path Seeker (GPS): modern high-speed LASSO-style regularized regression.
o Importance Sampled Learning Ensembles (ISLE): identify and reweight the most influential trees.
o Rulefit: ISLE on “steroids.” Identify the most influential nodes and rules.
V. Case Study Example:
o Output/Results without Post-Processing
o Output/Results with PostProcessing
