WebGradient is the direction of steepest ascent because of nature of ratios of change. If i want magnitude of biggest change I just take the absolute value of the gradient. If I want the unit vector in the direction of steepest ascent ( directional derivative) i would divide gradient components by its absolute value. • 4 comments ( 20 votes) edlarzu2 WebApr 10, 2024 · Gradient descent algorithm illustration, b is the new parameter value; a is the previous parameter value; gamma is the learning rate; delta f(a) is the gradient of the funciton in the previous ...
