这是通过“二次预训练”实现的，第一次预训练，我们让模型知道各个物体是什么；第二次预训练，我们通过“热力图”让模型重点关注操作对象，让模型学会分辨“什么才是当前任务最重要的东西”。
That depends on the type of keyboard. Since the Alice-split design simply rotates the keys apart, typing on it feels fairly similar to the regular keyboards you’re already used to. A fully split board will take a little more adjustment, particularly if it uses thumb clusters. The enter, shift and control buttons may now be operated by your thumbs instead of your other fingers and that can be tough to get used to. It took me a full month to get completely comfortable with a fully split keyboard with thumb clusters. But now, I prefer it to typing on regular boards.
