@tomstandage @alexismadrigal @cdixon We're more prepared for what AI will get right then grappling with what it'll get wrong, very weirdly.
@zeynep @alexismadrigal @cdixon There's that old apocryphal example of a neural network designed to recognise images containing tanks...
@zeynep @alexismadrigal @cdixon They trained the network and it got the trainign set 100% right. But was hopeless with new examples...
@zeynep @alexismadrigal @cdixon Turned out all training examples of tanks were taken on cloudy days, non-tanks on sunny days...
@zeynep @alexismadrigal @cdixon So the network had really learned cloudy/sunny distinction, not tank/non-tank. Ha ha
@tomstandage @alexismadrigal @cdixon Haha. But at least that makes some kind of sense.
