解决什么问题What problem it solves

给机器带答案的练习题,让它学会从题目推答案。Give the machine practice questions with answers, so it learns to derive answers from inputs.

这是什么What it is

训练数据每条都带正确答案,模型学着从输入推出答案。

常见任务分两类:预测连续数值叫回归,判断类别叫分类。

Every training example carries the correct answer; the model learns to map input to answer.

Two classic task families: predicting a continuous number is regression, deciding a category is classification.

为什么需要知道Why it matters

大模型的预训练并不属于这一类。分清它,你才知道模型是怎么练出来的。Pretraining a large model is not this kind of learning. Telling them apart is how you understand how models are actually trained.
