Explore CART, the classification and regression tree method, to build simple rules from data and split into homogeneous groups, laying the foundation for random forests.
Explore the CART framework and how decision trees split data into rules, using thresholds and metrics to minimize error, with leaves predicting averages.
Set up cart, explore from basics to advanced tree methods, and cover hyperparameter optimization, learning curves, visualization, rule extraction, and generating Python, SQL, and Excel outputs.
Deploy the final cart model using the decision tree classifier, tune min sample split and max depth via setparams and getparams, and evaluate with cross-validation metrics: accuracy, F1, and AUC.
Rank variables by their contribution to regression or classification tasks, minimize SSA and reduce Gini and entropy, then visualize their importance and note glucose, BMI, and age as top predictors.
visualize a classification and regression tree, generate a png diagram of the model, and explore splitting criteria such as gini and entropy with adjustable maximum depth.
Extract python codes, sql queries, and excel formulas to derive decision rules from a decision tree and deploy the model inside the database for in-database predictions.
