记录疑惑

A little knowledge is a dangerous thing.
一知半解是一件危险的事情。 -- Gentleman and Lady's Complete Magazine, Vol II, 1774

Confusion can be beneficial for learning, as some research shows that confusion when learning can be beneficial if it is properly induced, effectively regulated and ultimately resolved.

Confusion can be beneficial to learning if appropriately regulated because it can cause learners to process the material more deeply in order to resolve their confusion.

Writing down my confusion, and solving it subsequently.

一些研究表明,困惑有助于学习(Confusion can be beneficial for learning), 因为困惑会导致学习者更深入地处理材料,从而解决他们的疑惑, 并且能够将自己的知识应用于新问题。

但是,我不可能把所有产生的疑惑都立马去解决掉,因为我手头上常有更重要的事需要处理。但如果把疑惑放着不管,那就不符合我“打破砂锅问到底”的个性了。所以不妨把一些不便快速解决的疑惑记下来,以后再处理。

书中作者提到测量的list_len函数的CPE为4,我想知道他怎么测出来的。

注: 已经知道了,采用的线性拟合。增加元素的个数,拟合数元素个数和CPU始终的关系 (2021.02.25)
