    Effective Framework of J48 Algorithm using Semi

    The J48 algorithm comes under the decision tree classifier. We have selected this algorithm as it has the highest accuracy. One of the main benefits of the J48 classifier is that is relatively quick to train, and should finish almost immediately on a small data set. In this algorithm classification model is

    Feature Selection based Classification using Naive Bayes

    Constructing a classifier from probability model: For classification purposes Na ve Bayes classifier combines above model with decision rule. The commonly used rule is the maximum a posteriori or MAP decision rule. This rule selects the hypothesis which is most probable. 3.2 J48 In WEKA data mining tool J48 is implementation of

    Python Decision Tree Classification with Scikit-Learn

    Dec 28, 2018 Classification is a two-step process, learning step and prediction step. In the learning step, the model is developed based on given training data. In the prediction step, the model is used to predict the response for given data. Decision Tree is one of the easiest and popular classification algorithms to understand and interpret

    Provided the Weka classification tree learner implements the “Drawable” interface (i.e., provides a graph method), write_to_dot can be used to create a DOT representation of the tree for visualization via Graphviz or the Rgraphviz package. J48 generates unpruned or

    DECISION TREE APPROACHES There are two approaches for decision tree as:- 1) Univariate decision tree In this technique, splitting is performed by using one attribute at internal nodes. For ex. X 2, y =10 etc. There are many algorithms for creating such tree as ID3, c4.5 (j48 in weka) etc
