Keras-线性叠层? [英] Keras - Linear stack of layers?

问题描述

我开始按照本指南"学习如何制作神经网络，但是我已经被第一句话所困扰

I started to follow this "guide" to learn how to make a neural network but I'm already stuck at the first sentence

https://keras.io/getting-started/sequential-model-指南/

线性堆栈层到底是什么?

What the hell is a LINEAR stack of layer ?

这是否意味着堆栈的导数是常数? (开玩笑，但我对那些没有定义他们在说什么的向导感到非常沮丧)

Does it mean the derivative of the stack is a constant ? (kidding but I'm getting really frustrated by guides who don't define what they're saying)

推荐答案

线性堆栈是没有任何分支的模型.每一层都有一个输入和输出.一层的输出是其下一层的输入.

A linear stack is a model without any branching. Every layer has one input and output. The output of one layer is the input of the layer below it.

不是线性的堆栈可以具有带有多个输入和输出的层.它们之间的连接可能很复杂

Stacks which are not linear can have layers with multiple inputs and outputs. They can have complex connections between layers
