Artificial Intelligence / Unit 8 AI 0455 short lesson, about 20 seconds
The Learning Rate
Captions available
The idea
The stride of descent is the learning rate — and the anchor rule of modern training, each weight moving by stride times error times its own input, is the perceptron's nudge with a graded error.
In practice
The nudging rule was gradient descent wearing mittens; the smooth bend supplied the grading.
Where people slip
One procedure spans the unit — the continuity is the insight, not a coincidence.
