- 卷积神经网络中的batch到底是什么？ - 知乎
batch size：一般翻译为“批次大小”，表示训练过程中一次输入模型的一组样本的具体样本数量。前面提到了，我们在神经网络训练过程中，往往需要将训练数据划分为多个batch；而具体每一个batch有多少个样本，那么就是batch size指定的了。
- command line - What does the percent sign (% and %%) in a batch file . . .
The for command needs a placeholder so you can pass along variables for use later in the query, we are telling it use the placeholder %A, the reason the code you saw uses %%A is because inside a batch file (which I assume is where you found this) the % has a special meaning, so you must do it twice %% so it gets turned in to a single % to be passed to the for command

How does work in a Batch File? will execute the next command when the previous command returns 0 || will execute the next command when the previous command returns non 0; Almost all applications and utilities will set an Exit Code when they complete terminate:
- What is the meaning of tilde ~ in batch variables?
The tilde (~) sign is used in different ways in batch files: Argument quote removal A tilde sign before an command-line argument (such as "%~1") indicates to remove the surrounding quotes from the parameter
- How do I make an if and if statement in Windows Batch?
This one is more of a curiosity question, but is there a way in Windows Batch to be able to make an if file ext exists amp; amp; if file2 ext exists (echo Yes ) else (echo No ) -type command?
- 深度学习中的batch的大小对学习效果有何影响？ - 知乎
如果增加了学习率，那么batch size最好也跟着增加，这样收敛更稳定。 尽量使用大的学习率，因为很多研究都表明更大的学习率有利于提高泛化能力。 如果真的要衰减，可以尝试其他办法，比如增加batch size，学习率对模型的收敛影响真的很大，慎重调整。
- How can I execute a Windows command line in background?
killing explorer kills all explorer windows, I run this batch file after start up, so killing explorer is no issue for me You can seemingly have multiple explorer processes and kill them individually but I could not get it to work killing cmd exe is to close the CMD window which starts because of the bad apps erroring
- 深度学习中 Batch Normalization为什么效果好？ - 知乎
从上面可以看出，batch normalization依赖于batch的大小，当batch值很小时，计算的均值和方差不稳定。 研究表明对于ResNet类模型在ImageNet数据集上，batch从16降低到8时开始有非常明显的性能下降，在训练过程中计算的均值和方差不准确，而在测试的时候使用的就是训练
