WebThe Gradient = 3 3 = 1. So the Gradient is equal to 1. The Gradient = 4 2 = 2. The line is steeper, and so the Gradient is larger. The Gradient = 3 5 = 0.6. The line is less steep, and so the Gradient is smaller. WebApr 11, 2024 · The gradient ∂L/∂w is a vector in the increasing direction of the loss function. So, -∂L/∂w is a vector in the decreasing direction of L. Since η is greater than 0, and thus is a positive value, -η∂L/∂w is taking steps in the decreasing direction of L towards its minimum point. If η is a negative value, you are moving away from ...
