To overcome overfitting I have done optimization, data augmentation etc etc. I have an updated LR (I tried for both SGD and Adam), and when there is a plateu (also tried step), the learning rate is decreased by a factor until it reaches LR 1e-08 but won't go below than that and my model's validation gets stuck …

Nettet通常,像learning rate这种连续性的超参数,都会在某一端特别敏感,learning rate本身在 靠近0的区间会非常敏感,因此我们一般在靠近0的区间会多采样。 类似的, 动量法 梯度下降中(SGD with Momentum)有一个重要的超参数 β ,β越大,动量越大,因此 β在靠近1的时候非常敏感 ,因此一般取值在0.9~0.999。 Nettet28. okt. 2024 · Furthermore, I find that trying to "learn the learning rate" using curvature is not effective. However, there is absolutely no inconsistency in arguing that given we have settled on a learning rate regimen, that how we should alter it as we change the mini-batch can be derived (and is experimentally verified by me) by the change in curvature.
