A while back I posted a short, hopefully jocular, note about the machine learning algorithm for catching card counters at blackjack. Here is a more substantial article about the system. I wonder if systems like these will find use outside of gambling: anywhere an employee performs a repeated physical task (think a grocery store clerk?) and the company want to catch the errors. Boy those jobs are going to stink it up kind of rotten: “Johnny, if you make one more computer detected error tomorrow at the check stand, we’re going to have to let you go!” Is it better to be fired by a computer or by a human?
