- 卷积神经网络中的batch到底是什么? - 知乎
我们假设我们需要训练 3 个 epoch,相当于需要将这 1500 个样本训练 3 次。 那么, step 和 iteration 都会随着 epoch 的改变而发生改变——二者都变为 45,因为 15 * 3。 但是, batch 依然是 15,因为其是在每一个 epoch 的视角内来看待的,和 epoch 的具体大小没有关系。

论文 [1]。蓝色线:保持batch_size不变,而学习率在衰减。绿色线:首先学习率保持不变,而将批量大小增加,接着第一步之后,batch_size保持不变而学习率衰减。红色线:保持学习率不变,并且在每个步骤中将batch_size增加。 论文 [2]中提出一种线性缩放原则(Linear Scaling Rule),当batch size变大k倍时

iterations iterations(迭代):每一次迭代都是一次权重更新,每一次权重更新需要batch_size个数据进行Forward运算得到损失函数,再BP算法更新参数。 1个iteration等于使用batchsize个样本训练一次。 epochs epochs被定义为向前和向后传播中所有批次的单次训练迭代。

I have a question about if - else structure in a batch file Each command runs individually, but I couldn't use quot;if - else quot; blocks safely so these parts of my programme doesn't work How
- python - How big should batch size and number of epochs be when fitting . . .
The batch size should pretty much be as large as possible without exceeding memory The only other reason to limit batch size is that if you concurrently fetch the next batch and train the model on the current batch, you may be wasting time fetching the next batch (because it's so large and the memory allocation may take a significant amount of time) when the model has finished fitting to the

- 深度学习中的batch的大小对学习效果有何影响? - 知乎
这是肯定的,同样的epoch数目,大的batchsize需要的batch数目减少了,所以可以减少训练时间,目前已经有多篇公开论文在1小时内训练完ImageNet数据集。 另一方面,大的batch size梯度的计算更加稳定,因为模型训练曲线会更加平滑。
