Overfitting journey过拟合之旅
Three stops in the districts lab. Each link opens the same 24 districts with the bend already set. Draw a new set of districts before you treat one curve as the budget. Reset returns the bend to 3 and the noise to 0.3.在区的实验里停三站。每个链接打开同一批 24 个区，弯曲已经设好。把一条曲线当成预算之前，先再抽一批区。重置把弯曲回到 3，把吵闹程度回到 0.3。

A straight line一条直线
The trust pattern bends, and the line is not allowed to. Compare this year’s miss with next year’s.信任的形态是弯的，这条线不允许弯。比较今年的偏差和明年的偏差。

A gentle curve一条缓弯
The page’s starting point. The curve can follow the trust pattern more closely. Check whether next year’s miss agrees.这一页的起点。曲线可以更贴近信任的形态。看明年的偏差是否同意。

A curve that bends to every district弯向每一个区的曲线
This year’s miss can fall while next year’s miss stays large. Part of the curve may leave the window. The two miss numbers still count those districts. One set of 24 districts does not guarantee that more bend first helps and then hurts.今年的偏差可以下降，明年的偏差仍然大。曲线的一部分可能离开窗口。两个偏差数字仍计入那些区。一批 24 个区不能保证弯曲先有帮助、然后有害。
