WebAug 22, 2024 · Gradient descent in machine learning is simply used to find the values of a function's parameters (coefficients) that minimize a cost function as far as possible. You start by defining the initial parameter’s values and from there the gradient descent algorithm uses calculus to iteratively adjust the values so they minimize the given cost ... WebExample – Estimate the gradient of the curve below at the point where x = 2. Draw a tangent on the curve where x = 2. A tangent is a line that just touched the curve and doesn’t cross it.
