WebJun 24, 2014 · At a theoretical level, gradient descent is an algorithm that minimizes functions. Given a function defined by a set of parameters, gradient descent starts with an initial set of parameter values and … WebLines 9 and 10 enable gradient_descent() to stop iterating and return the result before n_iter is reached if the vector update in the current iteration is less than or equal to tolerance. This often happens near the minimum, where gradients are usually very small. Unfortunately, it can also happen near a local minimum or a saddle point. the park ruapehu
