Data Mining

A decision tree is pruned to get perhaps a tree that generalize better to independent test data We may get a decision tree that might perform worse on the training data but generalization is the goal See Information gain and Overfitting for an example Sometimes simplifying a decision tree

Decision Tree Algorithm in Data Mining

The decision tree algorithm formalizes this approach Data mining is the process of recognizing patterns in large sets of data When used with decision trees it can be used to make predictions based on the data To unlock this lesson you must be a Study Member

How Decision Tree Algorithm works

Jan 30 2017Introduction to Decision Tree Algorithm Unlike other supervised learning algorithms decision tree algorithm can be used for solving regression and classification problems too The general motive of using Decision Tree is to create a training model which can use to predict class or value of target variables by learning decision rules inferred from prior data training data

Decision Trees

The tree nodes are labeled with the names of attributes the arcs are labeled with the possible values of the attribute and the leaves are labeled with the different classes Decision trees were introduced in the Quinlans 1986 ID3 system one of the earliest data mining algorithms An item is classified by following a path along the tree
