Web14 de ago. de 2024 · In CS231 you have more degrees of freedom w.r.t the gradient and velocity terms, since their weights determined independently through alpha (lr) and beta, respectively. However, in NG version the weighting of lr and v is determined only by beta and after that alpha weights them both (by weighting the updated velocity term). WebThis work focuses on understanding the role of momentum in the training of neural networks, concentrating on the common situation in which the momentum contribution is fixed at each step of the algorithm, and proves three continuous time approximations of the discrete algorithms.
