May 17, 2024 · A decision tree is a flowchart-like structure used to make decisions or predictions. It consists of nodes representing decisions or tests on attributes, branches representing the outcome of these decisions, and leaf nodes representing final outcomes or predictions.
Decision tree analysis uses decision trees to assist with planning and making choices. Related choices are shown together in the decision tree and may include the probabilities of particular results along each branch.
A decision tree is a non-parametric supervised learning algorithm, which is utilized for both classification and regression tasks. It has a hierarchical, tree structure, which consists of a root node, branches, internal nodes and leaf nodes.
Mar 2, 2019 · To demystify Decision Trees, we will use the famous iris dataset. This dataset is made up of 4 features : the petal length, the petal width, the sepal length and the sepal width. The target variable to predict is the iris species. There are three of them : iris setosa, iris versicolor and iris virginica. Iris species.
