Is spam detection supervised or unsupervised?
Spam detection is a supervised machine learning problem. This means you must provide your machine learning model with a set of examples of spam and ham messages and let it find the relevant patterns that separate the two different categories. Most email providers have their own vast data sets of labeled emails.

The system tracks thousands of attributes of each message (for example, the words in the message or the sender’s IP address).
Why is naive Bayes used for spam detection?
Naive Bayes spam filtering is a baseline technique for dealing with spam that can tailor itself to the email needs of individual users and give low false positive spam detection rates that are generally acceptable to users. It is one of the oldest ways of doing spam filtering, with roots in the 1990s.
