Contour Plot of the Test Objective Function With AdaGrad Search Results Shown

Gradient Descent With AdaGrad From Scratch

Gradient descent is an optimization algorithm that follows the negative gradient of an objective function in order to locate the minimum of the function. A limitation of gradient descent is that it uses the same step size (learning rate) for each input variable. This can be a problem on objective functions that have different amounts […]
