DESCRIPTION:Spam is a given on the internet -- it's estimated that 55% of 
 all email is spam\, and each user receives almost 70 such emails per month
  [1]. It's used as a vehicle for all sorts of scams: phishing\, malware\, 
 419 advance-fee fraud and many other forms of malicious message are all co
 mmunicated via spam emails.  However\, real-world prevalence seems much lo
 wer due to filtering mechanisms put in place by email providers -- but how
  do they work?\n \nThis talk explores how a spam filter is built\, how the
 y have changed over time\, and various pieces of interesting Computer Scie
 nce that lurk within their implementation. Many of these techniques can al
 so be generalised beyond spam for application in other domains of classifi
 cation.\n\n[1] Symantec\, https://www.symantec.com/content/dam/symantec/do
