We will be using the KDD Cup 1999 data for this use case. The data is approximately 708 MB in size and contains 4.9 million network connections. The data comprises of information such as the following:

• Bytes sent
• Log-in attempts
• TCP errors
• Source bytes
• Destination bytes

The data contains 38 features in total. The features are categorized into both categorical and numerical data. The data collections also come with labels that help determine the purity of the clusters once the clustering algorithm has been applied.

The following is the list of all available features:

back,buffer_overflow,ftp_write,guess_passwd,imap,ipsweep,land,loadmodule,multihop,neptune,nmap,normal,perl,phf,pod,portsweep,rootkit,satan,smurf,spy,teardrop,warezclient,warezmaster.
