These are little computing units, but they're actually modeled on the way that the human brain does it's computation.

它们是很小的计算单元，但确实可以模拟人脑的计算方式。

Instead of being made of neurons, neural networks are made of a bunch of individual computing units, or nodes, that work together and are usually set up in layers.

神经网络不是由神经元组成，而是由一堆单独的计算单元或节点组成，它们一起工作并且通常分层设置。
