Which of the following machine learning algorithm is based upon the idea of bagging?Random-forestRegressionClassificationDecision treeSAVE
Solution
The machine learning algorithm that is based on the idea of bagging is Random Forest.
Here's a step-by-step explanation:
-
Bagging, or Bootstrap Aggregating, is a technique used to reduce the variance of an estimate. It works by creating multiple subsets of the original data, with replacement, and then using these subsets to get a better prediction.
-
Random Forest is a type of ensemble learning method, where a group of weak models combine to form a powerful model. In Random Forest, a set of decision trees are created.
-
Each of these trees is created from a different sample of rows and at each node, a different sample of features is selected for splitting. Each tree gives a "vote" for that class, and the class with the most votes becomes our model's prediction.
-
Regression, Classification, and Decision Tree are types of machine learning algorithms, but they are not specifically based on the idea of bagging. A Decision Tree could be a base learner in a bagging algorithm, but it is not inherently a bagging algorithm.
So, the answer is Random Forest.
