A decision tree is one of most frequently and widely used supervised machine learning algorithms that can perform both regression and classification tasks. The intuition behind the decision tree algorithm is simple, yet also very powerful. Everyday we need to make numerous decisions, many smalls and a few big. So, Whenever you are in … It continues the process until it reaches the leaf node of the tree. The complete process can be better understood using the below algorithm: Step-1: Begin the tree with the root node, says S, which contains the complete dataset. Step-2: Find the best attribute in the dataset using Attribute Selection Measure (ASM). A decision tree can be seen as a linear regression of the output on some indicator variables (aka dummies) and their products. In fact, each decision (input variable above/below a given threshold) can be represented by an indicator variable (1 if below, 0 if above). In the example above, the tree.A decision tree is a machine learning model that builds upon iteratively asking questions to partition data and reach a solution.

Decision trees are a common type of machine learning model used for binary classification tasks. The natural structure of a binary tree lends itself well to predicting a “yes” or “no” target. It is traversed sequentially here by evaluating the truth of each logical statement until the final prediction outcome is reached.
