Learning rate schedule 洪都拉斯的画 3 人赞同了该文章 学习率衰减(LR decay): 为了使训练开始时保证收敛速度,而在收敛到最优点附近时学习率要小一些 常用方法间nndl 学习率预热(LR warmup) 当batch大小的设置比较大时 ,一般需要比较大的学习率。但是在刚开始训练时,由于参数是随机初始化的,梯度往往比较大,...
An Exponential Learning Rate Schedule for Deep LearningZhiyuan LiSanjeev AroraInternational Conference on Learning Representations
学习率（Learning Rate，LR）作为超参数，对模型训练的效率和效果具有关键作用。在随机梯度下降（SGD）算法中，LR的大小直接影响模型的收敛速度和准确性。当Batch Size增大时，模型对数据的随机噪声的敏感度降低，这促使我们可以适度增加LR，以加快模型在负梯度方向的下降速度。有研究者提出了根据Batch Size...
Learning Rate Schedule:CNN学习率调整策略 本文同时发布在我的个人网站:https://lulaoshi.info/blog/learning-rate-schedule.html 学习率(Learning Rate,LR)是深度学习训练中非常重要的超参数。同样的模型和数据下,不同的LR将直接影响模型何时能够收敛到预期的准确率。
