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 …

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。 …

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 …

Jun 18, 2012 · I have a question about if - else structure in a batch file. Each command runs individually, but I couldn't use "if - else" blocks safely so these parts of my programme doesn't work. …

75 I received a line of code from someone who answered one of my questions, but I am confused: what do the "&&" do in this batch file.

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 …
