I'm gonna say back propagation for artificial intelligence.

我要说是人工智能的反向传播。

Back propagation will tell it how to change its AI brain so that it is better able to understand cats in the future.

反向传播将告诉它如何改变它的人工智能大脑，以便它在未来能够更好地理解猫。

But there's this little magic trick called back propagation and this is very unbiological-- Your neurons don't do this at all.

但是有一个叫做反向传播的小魔术，这是非常不符合生物学的——你的神经元根本不会这样做。

Back propagation is the few lines of code that tells an artificial intelligence algorithm, " If I see data, how can I become smarter based off of that data? "

反向传播是告诉人工智能算法的几行代码，“如果我看到数据，我如何根据这些数据变得更聪明？”
