Inmachine learning (ML), a decision tree is asupervised learningalgorithm that resembles a flowchart or decision chart. Unlike many other supervised learning algorithms, decision trees can be used for bothclassificationandregressiontasks. Data scientists and analysts often use decision trees when explorin...

What are decision trees? Decision tree is a powerful machine learning algorithm capable of performing regression and classification tasks. Also decision trees are the fundamental components of a range of ensemble models, such asRandom Forest and XGBoost.In decision tree, we predict that each observati...

The different types of machine learning explained How to build a machine learning model in 7 steps CNN vs. RNN: How are they different? They provide a clear visual representation of the entire decision-making process. This makes decision trees highly interpretable and easy to understand even for...
Decision treeis a popular Supervised learning algorithm which can handleclassificationandregressionproblems. For both problems, the algorithm breaks down a dataset into smaller subsets by using if-then-else decision rules within the features of the data. ...
