WEKA:The Command Line Interface

The Command-line Interface

Introduction
One can use the command line interface of Weka either through a command prompt or through the SimpleCLI mode
For example to fire up Weka and run J48 on a ARFF file present in the current working directory, the command is:
java weka.classifiers.trees.J48 -t weather.arff
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

Introduction

Structure of Weka
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
The structure of Weka can also be studied from the online Javadoc of Weka

Command line options
The -t option was used in the command line to communicate the name of the training file to the learning algorithm
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
