100 Days of Machine Learning | CampusX - Decision Trees Geometric Intuition | Entropy | Gini impurity | Information Gain

Decision Trees use metrics like Entropy and Gini Impurity to make split decisions. Entropy measures the disorder or randomness in a dataset, while Gini Impurity quantifies the probability of misclassifying a randomly chosen element. Information Gain, derived from these metrics, guides the tree in selecting the most informative features for optimal data splits, contributing to effective decision-making in classification tasks. ============================ Do you want to learn from me?
