WebFeb 9, 2024 · A gradient is a measurement that quantifies the steepness of a line or curve. Mathematically, it details the direction of the ascent or descent of a line. Descent is the action of going downwards. Therefore, the gradient descent algorithm quantifies downward motion based on the two simple definitions of these phrases. WebFeb 17, 2024 · Backpropagation, or reverse-mode differentiation, is a special case within the general family of automatic differentiation algorithms that also includes the forward mode.
