Gradient increase
WebJul 15, 2024 · This is, in a nutshell, a gradient:-) Visualizing Gradients. From the previous section, we already know that to minimize the loss, both b and w needed to be increased. So, keeping the spirit of using gradients, let’s increase each parameter a little bit (always keeping the other one fixed!). WebThe gradient vector tells you how to immediately change the values of the inputs of a function to find the initial greatest increase in the output of the function. We can see this in the interactive below. The gradient at each …
