Adam is an optimization algorithm that can be used instead of the classical stochastic gradient descent procedure to update network weights iterative based in training data. Adam was presented by Diederik Kingma from OpenAI and Jimmy Ba from the University of Toronto in their 2015 ICLR paper (poster) titled “Adam: A Method for Stochastic Optimizati...
Adam is different to classical stochastic gradient descent. Stochastic gradient descent maintains a single learning rate(termed alpha) for all weight updates and the learning rate does not change during training. A learning rate is maintained for each network weight (parameter) and separately adapted as learning unfolds. The authors describe Adam a...
Adam is a popular algorithm in the field of deep learning because it achieves good results fast. In the original paper, Adam was demonstrated empirically to show that convergence meets the expectations of the theoretical analysis. Adam was applied to the logistic regression algorithm on the MNIST digit recognition and IMDB sentiment analysis datase...
