Weka Tool for Classification:
Weka [1][2] is an open source tool widely used for performing various Machine Learning and Data Mining tasks. Weka is developed in Java.
Download the zip file for Weka from [1] and extract it. Change the directory to the extracted folder and enter the command
java -jar weka.jar
This will start the Weka GUI. Weka provides a lot of options for various data mining tasks like clustering, classification, preprocessing, feature extraction, etc. The important advantage of Weka is the visualization of results. We just need to load the data and start performing the necessary task.
