Introducing GIG: A new method for explaining any ensemble ML model
Who is this presentation for?Data scientists or analysts
Organizations are increasingly adopting ML to run key business functions. The best-performing models combine diverse model types (neural networks and trees) into stacked ensembles. But explaining these hybrid models with accuracy and precision has been impossible—until now.
Jay Budzik details the new explainability math called GIG that Zest developed. You’ll learn how GIG overcomes the limitations of and extends the commonly used methods shapley additive explanations (SHAP) and integrated gradients. Citing real-world examples, Jay also demonstrates how GIG makes it possible to explain complex ML models so they’re safe to use in high-stakes applications such as finance, healthcare, and defense.
- Familiarity with machine learning, including common techniques, such as neural networks, decision trees, logistic regression, etc.
What you'll learn
- Understand why using hybrid ML models produces better results than single-model techniques and why allocating credit is difficult when combining discrete and continuous functions
- Explore the limitations of SHAP and integrated gradients in explaining ensembled models
- Learn how measure theory resolves the problems of assigning feature importance
