First, install Weka

Before beginning you should download and install Weka – if it isn’t already installed, which it will be if you have done the previous course Data Mining with Weka.

(Note: Depending on your computer and system version, you may need admin access to successfully install Weka.)

  • Go to

  • Click the Download button

  • Now choose which one to download:

    • the latest version, currently Weka-3-8-3

    • (use the latest “stable” version; Weka-3-9 is a “developer” version)

    • the appropriate link for your computer; Windows, Mac, or Linux

    • if you don’t know what Java is, you probably want the file that includes a Java VM (= virtual machine)

Once it’s downloaded, Ian opens it to get a standard setup “wizard”.

  • Just keep clicking “Next”! Install it in the default place – and remember the name of that place!

  • After installation, uncheck the box that says “Start Weka” and click “Finish”.

  • Then go to where Weka was installed and

    • create a shortcut to the Weka program and put it on the desktop for future use.

    • make a copy of the data folder (within the Weka folder) and put it in a convenient place for future use

    • rename it “Weka datasets”
