Dr. James McCaffrey presents a complete end-to-end demonstration of decision tree regression from scratch using JavaScript. The goal of decision tree regression is to predict a single numeric value. For simplicity and better maintenance, the demo implementation uses list storage instead of pointers. For better customization and interpretability, the implementation uses list iteration instead of recursion or a stack algorithm.

Dr. James McCaffrey presents a complete end-to-end example of random forest regression to predict a single numeric value, implemented using C#. A random forest is a collection of basic decision tree regressors that have been trained on different subsets of the source training data. The technique reduces model overfitting to give more accurate predictions on new, previously unseen data.
