Random Forest Models in R with Tidymodels

Are you looking to harness the power of machine learning in R without getting lost in inconsistent syntax? Random forests are incredibly versatile and robust models, and the modern tidymodels framework provides a unified, elegant way to build them. This text-based course guides you from the absolute basics of random forest theory to training, tuning, and evaluating your own models. You will learn how to write clean, reproducible code and apply modern machine learning workflows to real-world datasets. What you'll learn: 1. Understand the core concepts of decision trees and how random forests combine them for better predictions. 2. Configure model specifications using the parsnip package within the tidymodels ecosystem. 3. Prepare and preprocess your data cleanly using recipes for optimal model performance. 4. Tune hyperparameters like tree depth and active predictors to optimize your model's accuracy. 5. Evaluate model performance using cross-validation and key metrics like RMSE and ROC AUC. 6. Implement reproducible workflows by properly managing random seeds and resampling folds. We begin with foundational definitions and key terminology before moving step-by-step through data preparation, model training, hyperparameter tuning, and final evaluation. You will read clear explanations and study structured code snippets designed to make these concepts easy to grasp. This course is designed for beginners who have a basic familiarity with R and want to step into the world of tidy machine learning. No prior experience with predictive modeling is required.
