Jan 8, 2019 · In Machine Learning, tree-based techniques and Support Vector Machines (SVM) are popular tools to build prediction models. Decision trees and SVM can be intuitively understood as classifying different groups (labels), given their theories. However, they can definitely be powerful tools to solve regression problems, yet many people miss this fact. At a basic level, a decision tree is a machine learning model that learns the relationship between observations and target values by examining and condensing training data into a binary tree. Each leaf in the decision tree is responsible for making a specific prediction. For regression trees, the prediction is a value, such as price.
