Web29 nov. 2024 · In conclusion, this paper clarifies the inequivalence of L_2 regularization and weight decay for Adam, and decouples weight decay from the gradient-based update, which is AdamW. It has better generalization performance compared with Adam, and yields a more separable hyperparameter space for tuning. In the next paper, we can see … WebHowever, SGD with momentum seems to find more flatter minima than Adam, while adaptive methods tend to converge quickly towards sharper minima. Flatter minima generalize better than sharper ones. Despite the fact that adaptive methods help us tame the unruly contours of a loss function of a deep net's loss function, they are not enough, …
