Two new research papers explore the nuances of the Adam optimizer, a popular tool in deep learning. The first paper proposes a "refresh rule" for Adam's momentum parameter, suggesting it should scale with training data size to optimize performance and robustness across different scales. The second paper delves into how mini-batch noise, influenced by batch size and Adam's hyperparameters, affects the optimizer's implicit bias and generalization capabilities, particularly in multi-epoch training scenarios.
