Making statements based on opinion; back them up with references or personal experience. @JosefSbl, GD has been phased out more than 6 years ago; the question of backward compatibility is no longer relevant. In this case, GD would be a positive or affirmative response to something. So lets dive deeper in the deep learning models to have a look at gradient descent and its siblings. The Minibatch combines the best of both worlds. On the other hand, using SGD will be faster because you use only one training sample and it starts improving itself right away from the first sample. Bring back the discussion on the track, if the group is deviating from the topic. So, the idea is to pass the training set through the hidden layers of the neural network and then update the parameters of the layers by computing the gradients using the training samples from the training dataset. Find centralized, trusted content and collaborate around the technologies you use most. Their numbers have also been rising over the past few years. When we say that we are training the model, its gradient descent behind the scenes who trains it. Its not like the one variant is used frequently over all the others.
