Good to have Dominic back
"Neural Networks were a joke in the 1980s. I built one, for a given value of "built" since it never ever did anything useful or even go wrong in a particularly interesting way."
Some Transputer-using friends got a bit further than Dominic, then... they trained their neural net with photos of team members, using a wheelie bin as control. Despite their best efforts, the net never managed to distinguish the bin from the team's rugby-playing member.
