Derivative algorithm
WebJul 9, 2024 · The best way to understand this derivative is to realize that f (x) = x is a line that fits the form y = mx + b because f (x) = x is the same as f (x) = 1x + 0 (or y = 1x + 0). The slope (m) of this line is 1, so the derivative equals 1. Or you can just memorize that the derivative of x is 1. WebNewton's method in optimization. A comparison of gradient descent (green) and Newton's method (red) for minimizing a function (with small step sizes). Newton's method uses curvature information (i.e. the second derivative) to take a more direct route. In calculus, Newton's method is an iterative method for finding the roots of a differentiable ...
