我对于学习的方法论
Q: In your opinion, how to study? (Including formal science, nature science, social science, humanity and anything else)
A:
math, physics, statistic | chemistry, biology, psychology, social science, humanity | CS/EE, programming language, nature language, exercise, music, cook, poem, drawing, video game | |
---|---|---|---|
Search the Internet/Book | √ | √ | √ |
Deduction | √ | × | × |
Mind Map | × | √ | × |
Practice | × | × | √ |
Q: Do you have anything to supplement?
A:
- × and √ are not 0 and 1, not “never” and “always”, but “seldom” and “usually”.
- We can interpret the result from the point of view of neuroscience.
- Language (both programming and natural) is more like non-declarative memory
- Math, biology are more like declarative memory
- Comp Neuro, AI, ML, DL, RL are the inter-discipline of math, biology and CS, so need them all.
Q: Why you never use the pdf of C, Data Structure after the course?
A: They are too out-of-date. Just practice! Don’t be a nerd! Don’t learn English or Python in the class, just practice!
问:你曾说,有两个习惯是转型1的关键,第一是瞬发搜查+瞬发整合,第二是默推,你还这么认为吗?
答:瞬发搜查、默推没问题,对于瞬发整合,我有一点补充意见。
上课时,不能老师说一句话,我记一句话,我要滞后一些,有我自己的思考。
看视频时,不能小林说一句话,我记一句话,我同样要滞后一些,有我自己的思考。
说白了,有自己的思考比瞬发更重要!
没有思考的复制粘贴,还不如不复制粘贴!立刻删掉!
问:转型2的关键是什么?
答:
- 瞬发搜查、整合当然还是需要的。是否需要默推取决于你干啥,不同领域推公式/写代码/做实验的时间比例不一样。
- 如果你已经有良好的搜索习惯了(事实上,没这习惯恐怕到不了转型2),那么,转型2的关键不是搜索,而是——转换思维,从学别人的到突破人类极限,从书本上到实践中,从站在学生的角度思考到站在Fisher的角度思考。
问:纸笔、OneNote、GoodNote、Markdown Note、思维导图,你如何选择?
答:看心情。
这有一个经验规律,但我也不是每次都遵守。

问:在科研阶段,如何尽量让碎片知识整体化?
答:尽量往书籍、课程、实验室上靠。具体来说
- paper尽量往book上靠。
- talk尽量往class上靠。
