WebFinding the minimum of a function f f, is equivalent to calculate f(m) f ( m). To find m m, use the derivative of the function. The minimum value of a function is found when its … WebMar 29, 2024 · Gradient descent is an optimization algorithm that is used to minimize the loss function in a machine learning model. The goal of gradient descent is to find the set of weights (or coefficients) that minimize the loss function. The algorithm works by iteratively adjusting the weights in the direction of the steepest decrease in the loss function.
