Artificial Intelligence / Unit 8 AI 0453 short lesson, about 20 seconds
The Error Landscape
Captions available
The idea
Training a smooth machine is walking on a landscape: the knob settings are a position, the total error is the altitude, and learning is descending.
In practice
One knob makes the landscape a curve; a million make terrain no one can picture — the walking rule is unchanged.
Where people slip
The picture is exact, not metaphor — every training step is a step on this ground.
