Purpose of gradient descent
In mathematics, gradient descent (also often called steepest descent) is a first-order iterative optimization algorithm for finding a local minimum of a differentiable function. The idea is to take repeated steps in the opposite direction of the gradient (or approximate gradient) of the function at the current point, because this is the direction of steepest descent. Conversely, stepping in the direction o… WebThe purpose of Gradient descent technique is to found set that leads to the minimum loss function value possible. In this paper we introduce common optimization technique and their challenges and how this leads to the derivation by using their update rules.
