Gradient Descent
Updating weights in the direction that reduces the loss.
Aperçu
Gradient descent adjusts each weight by a small step opposite the gradient, repeating until the loss stops falling. It solves the problem of finding a good configuration in a space far too large to search. It exists as the simplest member of a family of optimisers, and the practical work is in choosing the step size, the batch size and the schedule rather than in the update rule itself.
