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 …

Jan 21, 2021 · I have seen the usage of %* in batch files and command lines. Can someone explain the typical usage of %* with an example?

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.

It's the same as 'if "%1" == "" goto somewhere', except that will fail in batch files, because "" evaluates to nothing and the whole sentence reduces to 'if %1 == goto somewhere'. I prefer X, since ! makes you …

batch size 需要 调参 可以确定的是， batch size 绝非越大越好。 因为 batch size 的极限是训练集样本总个数，而这是当初神经网络还未如此之火时的训练方式 Gradient Descent (GD)。 2014 年初我上的 …

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。 …

Apr 14, 2022 · 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 …
