Decision Tree in RapidMiner
I explain how to create a decision tree model for the multi-class classification problem in this tutorial. The IRIS data set is utilized. Preprocessing, selecting the target variable, and splitting the data into a training and test set are all done. A decision tree classifier is then built using the training set and its performance on both the training set and test set are measured. The results are further explained.
