以下内容摘自<Bag of Tricks for Image Classification with Convolutional Neural Networks>. 1 高效训练 1.1 大batch训练 当我们有一定资源后,当然希望能充分利用起来,所以通常会增加batch size来达到加速训练的效果.但是,有不少实验结果表明增大batch size可能降低收敛率,所以为了解决这一问题有人以下方法可供选择: 1.1.1 线性增加学习率 一句话概括就是batch size增加多少倍,学习率也增…

一.高效的训练     1.Large-batch training 使用大的batch size可能会减小训练过程(收敛的慢?我之前训练的时候挺喜欢用较大的batch size),即在相同的迭代次数下, 相较于使用小的batch size,使用较大的batch size会导致在验证集上精度下降.文中介绍了四种方法. Linear scaling learning rate 梯度下降是一个随机过程,增大batch size不会改变随机梯度的期望,但是减小了方差(variance).换句话说,增大…
