But this example shows the potential costs of a signal error and the importance of studying the effects of noise on those strategies.

但这个例子显示了信号错误的潜在成本以及研究噪声对这些策略的影响的重要性。

If the buffer is ready or the endpoint is stalled at some USB thing to signal errors, then you can break out of this loop.

如果缓冲区准备就绪或端点在某些 USB 设备上停止以发出错误信号，则您可以跳出此循环。

If the network is shown an image of a bird but mistakenly concludes that it is not, then—once it realises the gaffe—it generates an error signal.

如果向网络展示一张鸟的图像， 但错误地认为它不是鸟，那么一旦它意识到失误， 它就会生成错误信号。

For backpropagation to work in the brain, a perfect mirror image of each network of neurons would therefore have to exist in order to send the error signal backwards.

为了使反向传播在大脑中发挥作用，每个神经元网络必须存在一个完美的镜像，以便将错误信号向后发送。
