Dr. James McCaffrey presents a complete end-to-end demonstration of decision tree regression from scratch using the C# language. The goal of decision tree regression is to predict a single numeric value. The demo implementation uses pointers (references) for efficiency but does not use any recursion for better maintainability and customization.
