Tutorial + Hands-on
Timeframe
2 hours (Tutorial) + 4 hours (Hands-on)
Description
Scope
This tutorial and hands-on aim to provide participants with a comprehensive understanding of SHAP for interpreting machine learning models. The scope includes an explanation and exploration of SHAP principles, practical implementations, and considerations for model interpretation. Participants will gain proficiency in leveraging SHAP values to enhance the explainability of machine learning models across various scenarios, including dealing with unbalanced data, collinear features and the nuanced relationship between causality and correlation.
Proposed Timeline
Tutorial (2 hours)
Introduction to SHAP (15 mins)
· Overview of SHAP principles
· Importance of explainability in machine learning
Why Use SHAP? (15 mins)
· Identifying scenarios for the SHAP application
· Understanding the benefits and limitations of SHAP
· Differentiation of SHAP usage to other XAI tools
When to Use It? And When Not to Use It? (15 mins)
· Providing guidance on when in a project to use SHAP (and when not to)
· Highlighting scenarios (and stages of a project) where SHAP may not be suitable
How to Use SHAP (15 mins)
· Integrating SHAP into machine learning workflows
Caveats: Collinear Features / Causality <-> Correlation / Unbalanced data (20mins)
· Exploring common pitfalls and best practices
Model Interpretation and Reporting (30 mins)
· Translating SHAP outputs into meaningful model interpretations
· Guidelines for reporting SHAP results in research papers
· What we can say about our models with the help of SHAP and what not.
Hands-on Workshop (4 hours)
Practical Implementation (2 hours)
· Participants work through hands-on exercises using SHAP
· Real-world examples to reinforce understanding
Group Discussions and Q&A (1 hour)
· Addressing participant queries and concerns
· Facilitating group discussions on SHAP application challenges
Project Work (1 hour)
· Participants apply SHAP to their datasets or models
· Guidance and feedback from instructors
By the end of the course, participants will have a foundation in SHAP, enabling them to effectively evaluate the cases when applying this technic and how to communicate the interpretability of machine learning models in their respective domains.
