WebThe gradient of a function results then the del operator acts on a scalar producing a vector gradient. The divergence of a function is the dot product of the del operator and a vector valued function producing a scalar. When we use Mathematica to compute Div, we must remember to input the components of a vector. If we wish to find the ... WebApr 25, 2024 · Gradient descent consists of iteratively subtracting from a starting value the slope at point times a constant called the learning rate. You can vary the iterations into gradient descent, the number of points in the dataset, the seed for randomly generating the points and the learning rate.
