WebGradient descent is an optimization algorithm that iteratively reduces a loss function by moving in the direction opposite to that of steepest ascent. The direction of the steepest ascent on any curve, given the initial point, is determined by calculating the gradient at that point. The direction opposite to it would lead us to a minimum fastest.
