Training
解决什么问题What problem it solves
让模型从数据里学会规律，产出这个模型。Let the system learn its parameters from data by repeated exposure.
这是什么What it is
用数据反复调整模型参数的过程。跑完训练得到的是一个「模型」。
训练成本极高，普通公司和个人基本不可能从头训一个大模型。
Fitting parameters so predictions match targets, usually by minimising a loss over many examples.
为什么需要知道Why it matters
它和「推理」是一对概念。分清这两个词，你就明白为什么模型能下载、但没人能「训」你手里这个。Training determines what the model knows. It is also where cost and bias enter — training data is not neutral.
