Lee Sedol is playing brilliantly! #AlphaGo thought it
was doing well, but got confused on move 87. We
are in trouble now...
Mistake was on move 79, but #AlphaGo only came to
that realisation on around move 87
When I say 'thought' and 'realisation' I just mean the
output of #AlphaGo value net. It was around 70% at
move 79 and then dived on move 87
Lee Sedol wins game 4!!! Congratulations! He was
too good for us today and pressured #AlphaGo into
a mistake that it couldn’t recover from
