Decision tree pruning youtube. Jul 23, 2025 · In this guide, we will walk through how decision trees work, from splitting the data to pruning the tree to prevent overfitting. Feb 2, 2026 · Decision trees, when allowed to grow freely, tend to learn noise and very specific patterns from the training data, leading to overfitting. Pruning addresses this issue by simplifying the tree structure, improving generalization to unseen data, enhancing interpretability and reducing computational cost, while maintaining or even improving overall model accuracy. Lecture 49 : Pruning in Decision Trees || Machine Learning Python Course PhysicsMania-Mohit Gupta [IIT BHU] 5. Pruning Decision Trees falls into 2 general forms: Pre-Pruning and Post-Pruning. 99K subscribers Subscribed. Then Pruning Regression Trees is one the most important ways we can prevent them from overfitting the Training Data. This video walks you through Cost Complexity Pruning, aka Weakest Link Pruning, step Decision Tree Pruning explained (Pre-Pruning and Post-Pruning) How to Prune Regression Trees, Clearly Explained!!! Pruning Citrus Trees: Lemons, Limes, Oranges and More ]: Part 10 of the video talks about how to use decision trees for regression analysis in R. The following figure illustrates the effect of using 20% of the dataset as validation to prune the decision tree Overfitting is a common problem with Decision Trees.
