Welcome to the workshop!
Welcome to Evaluating Model Performance with Ensemble Methods!

Today's icebreaker:
Share one instance where accurate predictive modeling influenced a business decision you’ve seen or read about.
Put you answers in the chat.
Today's agenda:
ReviewRecap key concepts from async units 1 and 2.15 minsDemoWe'll provide a guided walkthrough of how to:
-
Prepare and clean your data.
-
Train ensemble classifiers such as Random Forest, Gradient Boosting, XGBoost.
-
Apply the hyperparameter optimisation techniques GridSearchCV and RandomizedSearchCV. 10 minsPracticeYou'll get hands-on with the ensemble methods for model evaluation shown in the demo.25 minsClosingKey takeaways and next steps.10 mins## Today's learning objectives:
-
Implement and interpret ensemble methods** **(Random Forest, Gradient Boosting, XGBoost) for classification tasks, identifying their relative strengths in improving predictive accuracy.
-
Evaluate ensemble model performance rigorously using metrics including accuracy, precision, recall, and confusion matrices, effectively communicating results.
-
Apply hyperparameter tuning techniques (GridSearchCV, RandomizedSearchCV) to optimise ensemble classifiers for specific business contexts.
-
Make data-driven recommendations based on ensemble model evaluations, effectively translating technical results into actionable business strategies, specifically in customer-retention scenarios.
