其實我而加讀緊ma既感覺都係prof比一大堆書你睇
唔會好詳細咁同你解D野
然後就寫文等佢比comment

好多時同自學無分別 去到PhD我估計要再independent得多

好似我而家d research, 其實都係傾之後自己搵方法做,佢咁樣其實係為你好 訓練你做一個independent researcher


“Train you to be an independent researcher” 呢句我supervisor成日講

所以我覺得愈放手既prof 同 supervisor, 其實係最好 但放手唔等於唔理/無視

岩呀 但係有d就無視當放手

Somehow又同老細年資/地位有關
通常年資淺既會緊張好多,一來要chur tenure track,二來新手老豆,唔會/唔識俾時間你錯

文科讀PhD有咩做
齋睇書之後就出論文?

ling通常唔係做lab就係做 fieldwork寫 grammar lexicon

再唔係就 computational嘅 modeling或者用 corpus搞啲 statistical analysis

當然而家興 combine

例如我老細就係半 experimental半 computational

好似係用論據去論證
不過有啲都會用quantitative method
例如中文科現代用語,會survey target population

如果係文學果啲,聽過會研究點樣改善一啲文體,就會用到好多古代現代文學作者用法既變化,再加入自己既想法,得出啲修改方法之類,其實都好多野玩,用quantitative and qualitative search咁分

利申: 聽巴士佬講然後自己鳩up

Optimization 其實學乜野

點optimize某objective subject to 唔同constraint (equality or inequality)
幾時有solution, 點計呀etc
深啲既有dynamic optimization, decision making over time etc.

like high school finding local maximum pt/minimum pt

Dynamic programming

讀緊game theory,入面有好多simplex optimization,用手計計到頭暈

Agger 好煩 nash bargaining solution


Dynamic programming 已經好好做。
Behavioral econ 有啲咩multi-selves agent, dynamically inconsistent agent, 連dynamic programming 都唔apply,煩到嘔泡。
Nash bargaining 亦都係最簡單,有幾多relationship中的surplus只係按bargaining power分。

好在我唔係modeling個邊

optimization其實係好正既topic 我做緊machine learning research
Machine learning入面好多algorithm 都係solve optimization problems
當中會用到好多real analysis同functional analysis既techniques
最正個位係可以自己諗某啲algorithms去solve某一類optimization problems然後paper

functional 同 real analysis 都好正

巴打講多啲 QM有好多banach space,想知多啲functional analysis做啲咩

我d FA已經唔記得七七八八 , 我更加唔識物理
某D Linear PDE可以用functional analysis的方法去deduce d property
e.g. compact operators
又可以用黎construct measures, e.g. Haar measure
同埋functional analysis本身會deal with d Banach / Hilbert spaces, 但係數學本身都會遇到呢D spaces, e.g. space of continuous functions, L^p spaces等等
probability都會見到, e.g. weak convergence
所以functional analysis算係analysis的基礎野 又要準備溫書考qualifying

analysis好難讀 巴打一定好醒目

巴打今個sem上莫毅明個anal?

自己睇下書咋,未take.諗住等下個sem鬼佬教會好grade D

係,ben kane教一定會好過莫毅明

原先對qualitative都有啲興趣,master上過qualitative之後, 差啲想自殺
感覺就同遇到cog psy一樣,未學前覺得好counter intuitive, 學完之後完全唔想再做

不過mental process 例外

之前同個philo教授吹水,佢話philo都有人做quantitative 例如用probabilistic model諗ethics,utilitarianism

有呀,ethics超多
然後套用philo theories黎解釋

Argument當然一樣重要嘅

There is no magic about numerical methods, and many ways in which they can break down. They are a valuable aid to the interpretation of data, not sausage machines automatically transforming bodies of numbers into packets of scientific fact. - F.H.C. Marriott
