Looking at the quiver plot in NG’s Lab 04, the direction of arrows at (w = 400, b = 100) seems to be away from the direction in which the steps have to be taken to reach the 0 gradient, can someone help me understand what the direction in this quiver plot indicates?
Hello @abhilash341,
Remember that we have a minus sign in the gradient descent update formula?
Cheers,
Raymond
