解决什么问题What problem it solves

不手写规则,直接给机器大量例子,让它自己总结规律。Instead of writing rules by hand, let the machine find patterns in data.

这是什么What it is

让计算机从数据里自动找出规律、并用规律对新情况做预测或分类的一类方法。

和传统编程的区别:传统是你写「规则」,机器学习是你给「例子」,规则由它自己总结。

A method where a system improves at a task by fitting parameters to examples, rather than following rules a programmer wrote.

为什么需要知道Why it matters

它解释了 AI 为什么需要大量数据和算力。这不是玄学,是这类方法的本质要求。It is the foundation under essentially everything called AI today. Knowing where the rules came from tells you what the system can and cannot do.
