The Error Landscape
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
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.
Show
One knob makes the landscape a curve; a million make terrain no one can picture — the walking rule is unchanged.
Watch for
The picture is exact, not metaphor — every training step is a step on this ground.
