    J48 Classifier Parameters 1 Overview Very similar to the commercial C4.5, this classifier creates a decision tree to predict class membership. Decisions trees are also sometimes called classification trees when they are used to classify nominal target values, or regression trees when they are used to predict a numeric value

    J48 is an open source Java implementation of simple C4.5 decision tree algorithm. J48 is an extension of ID3. The additional features of J48 are accounting for missing values, decision trees pruning, continuous attribute value ranges, derivation of rules, etc. Being a decision tree classifier J48 uses a predictive machine-learning model
