Incorrectly Classified Instances 8 5.3691 % Trying to add database driver (JDBC): jdbc.idbDriver - Error, not in CLASSPATH?Ĭorrectly Classified Instances 141 94.6309 % Here are the corresponding command lines: We perform the same operation for GridDB. Make sure to add the Weka library path to CLASSPATH. GridDB 4.6: After installation, a GridDB cluster has to be active. Weka 3.9: Download and place weka.jar file in the /usr/share/java/ path. In this section we describe the requirements and configuration used in this article. In this case, we write the original dataset into GridDB, we store the data, and we retrieve it for its later use to build the decision tree. After that, we describe different interactions with GridDB, which is our main database. Later, the implementation of the algorithm using the Weka J48 decision tree is presented. The article begins by describing the dataset used in this article. This article describes the implementation of a decision tree algorithm in Java. These methods have acquired the importance to become vital in different sectors and industries. The combination of statistical methods, machine learning, and artificial intelligence have allowed the development of various data mining techniques that serve as support systems in many fields.
