Visualizing Decision Trees: The Ultimate Guide
About this lesson
This video quickly walks through building a decision tree with simple animal examples (Can Fly, Lays Eggs, Eats Meat) to classify bird vs not bird, shows how we pick the best splits using Gini Impurity and weighted impurity reduction, covers handling multi-valued and continuous features with one-hot encoding and optimal thresholds, explains how to avoid overfitting using pre-pruning and post-pruning, and wraps up with a plain-English intro to Random Forests using bootstrapping, random feature subsets, and combining many trees for more stable, accurate predictions. chapters:- 0:00 Introducing Decision Trees 3:19 Measuring Impurity 4:52 Training Efficient Decision Tree 7:58 Brief Introduction to pruning 8:45 Dealing with non binary data 10:35 Regression Trees 13:39 Random Forest Link to video on Training-validation-Testing data:- https://youtu.be/C-Cd2ZGXBH4 📚 Welcome to the Channel!
