A decision tree algorithm is a machine learning algorithm that uses a decision tree to make predictions. It follows a tree-like model of decisions and their possible consequences. The algorithm works by recursively splitting the data into subsets based on the most significant feature at each node of the tree. The main principle behind the ensemble model is that a group of weak learners come together to form a strong learner. Let’s talk about few techniques to perform ensemble decision trees: 1. Bagging. 2. Boosting. Bagging (Bootstrap Aggregation) is used when our goal is to reduce the variance of a decision tree.
