Once you have the gradient vector, which points uphill, just go in the opposite direction to go downhill.
Nettet25. apr. 2024 · Because it is not always possible to solve for the minimum of this function, gradient descent is used. Gradient descent consists of iteratively subtracting from a starting value the slope at point times a constant called the learning rate.
