WEKA:The Command Line Interface

  1. 1. The Command-line Interface<br />
  2. 2. Introduction<br />One can use the command line interface of Weka either through a command prompt or through the SimpleCLI mode<br />For example to fire up Weka and run J48 on a ARFF file present in the current working directory, the command is:<br />java weka.classifiers.trees.J48 -t weather.arff<br />Weka consists of a hierarchical package system. For example here J48 program is part of the treespackage which further resides in the classifier package. Finally the wekapackage contains the classifiers package<br />
  3. 3. Introduction<br />
  4. 4. Structure of Weka<br />Each time the Java virtual machine executes J48, it creates an instance of this class by allocating memory for building and storing a decision tree classifier<br />The structure of Weka can also be studied from the online Javadoc of Weka<br />
  5. 5. Command line options<br />The -t option was used in the command line to communicate the name of the training file to the learning algorithm<br />If you invoke a scheme without any command-line options at all, it displays the applicable options: first the general options, then the scheme-specific ones<br />
  6. 6. Command line options<br />General options<br />
