Gini Index or Gini impurity measures the degree or probability of a particular variable being wrongly classified when it is randomly chosen. But what is actually meant by ‘impurity’? If all the elements belong to a single class, then it can be called pure. The degree of Gini Index varies between 0 and 1, where, '0' … See more We are discussing the components similar to Gini Index so that the role of Gini Index is even clearer in execution of decision tree technique. The … See more Entropy is a measure of the disorder or the measure of the impurity in a dataset. The Gini Index is a tool that aims to decrease the level of entropy from the dataset. In other words, entropy is the measurement of the impurity or, we … See more Let us now see the example of the Gini Index for trading. We will make the decision tree model be given a particular set of data that is readable for the machine. Now, let us … See more The formula of the Gini Index is as follows: Gini=1−n∑i=1(pi)2Gini=1−∑i=1n(pi)2 where, ‘pi’ is the probability of an object being classified to a particular class.
