Artificial Intelligence / Unit 8 AI 0460 short lesson, about 20 seconds

Captions available
The idea
A trained deep network's theory of its task is written in millions of coupled knobs and cannot be read — verification shifts from reading machines to testing behavior.
In practice
The melon machine said yellowness, three to one; a deep stack's knowledge lives in no readable clump of knobs.
Where people slip
Remember the perceptron's courtesy — audit, contest, check — pricing its loss keeps the next units honest.
