WebJul 12, 2024 · Thanks to theorem 2.8, we now know that Nesterov's accelerated gradient method converges weakly to a solution from the solution set in case of exact data , i.e. . Hence, it remains to consider the behaviour of in the case of inexact data . As mentioned above, the key for doing so is inequality . WebWhen performing gradient check, remember to turn off any non-deterministic effects in the network, such as dropout, ... We recommend this further reading to understand the source of these equations and the mathematical formulation of Nesterov’s Accelerated Momentum (NAG): Advances in optimizing Recurrent Networks by Yoshua Bengio, Section 3.5. WebSimpler methods like momentum or Nesterov accelerated gradient need 1.0 or less of model size (size of the model hyperparameters). Second order methods (Adam, might need twice as much memory and computation. Convergence speed-wise pretty much anything is better than SGD and anything else is hard to compare. affinity essential provider login
