Is Rectified Adam actually *better* than Adam?博狗的备用网站

Is the Rectified Adam (RAdam) optimizer actually better than the standard Adam optimizer? According to my 24 experiments, the answer is no, typically not (but there are cases where you do want to use it instead of Adam). In Liu et al.’s 2018 paper, On the Variance of the Adaptive Learning Rate and Beyond, the […]
