How do spam filters actually work and what does this have to do with maths?

Who doesn't know it: The mailbox is full of spam messages of all kinds. These unwanted mails can be filtered automatically with the help of mathematics. For this purpose the incoming mails are sorted into two different classes "Spam" and "Ham".

In the workshop, we will get to know and use Bayes' theorem to create a spam filter together and test it with real mails.
