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

我只係數學系的地底泥

Kinli既analysis已經讀唔好

唔敢讀real an/fa

Kin Li 科Analysis係學唔到任何野, 自修把啦

點先可以讀好mathematical analysis
2017-03-22 01:00:48

我趕唔切火車
下個星期再見佢 唔知會唔會被屌

俾我係advisor都屌你

做人公平d好 我都俾唔少prof放過飛機

我個prof覆email好慢,成日約唔到時間

之前有個prof隔三個月先覆我
之後我睬佢都戇鳩

我聖誕搵佢,佢農曆新年先黎覆我,仲加句merry christmas

Pp analysis 但係我都係得mean
有諗過去讀complex不過又唔多岩用

Last一個sem Optimization又懶得上 遲下問fd拎notes睇好過

其實唔駛做Rudin咁誇張, 佢D exercise設計唔係話好, 當你適應左之後會覺得Baby rudin唔太難
做Bartle Tao果D會好D

Tao本Analysis真係好撚詳細, 係mulcal之前仲會recall返D linear algebra

而加係UK讀緊taught master,politics野,想繼續讀上去,有d野想問大家

我暫時有兩個offer
一個係Warwick PhD
一個係Oxford Master in Research(讀一年),讀得ok就可以transfer過PhD

如果兩個都無funding既話,我應該會過oxford

但如果Warwick oxford都有funding既話,應該點揀好?我有呢D顧慮 :

1) 我同warwick個邊既supervisor關係較好,佢係我個field到都有咁上下出名。如果warwick比funding,我都照去oxford有d擔心會影響佢對我既印象

2) 我知道warwick畢業如果係英國搵同學術有關既工作唔難,但如果我之後最想返返香港做野,warwick出黎會唔會比oxford出黎輸蝕?

3) 如果我讀oxford唔揀warwick,我之後就要再次同其他人爭funding,而funding既競爭係好激烈,之後隨時一間都唔會比

4) 係oxford讀完個msc,就算無得原校上phd,上返lse/ucl/king's/anu/warwick 等tier既學校都會較容易(當然前提係我要係而加讀緊既master拎到distinction)

5) 我warwick supervisor以前oxford出黎,佢話個邊既supervisor唔會好認真比comment你,好多時都係等個phd自生自滅

我應該點揀 真心想聽下大家意見

回樓上幾位巴打:

其實我oxford個邊既formal offer letter未出...只係department比左informal offer letter我,話已經收左我,但未知supervisor會係邊個

不過我apply oxford個時 indicate左一個oxford prof做我supervisor
而個位oxford prof係我warwick supervisor讀phd個時既師父

個oxford prof收到我份application個時email過我warwick supervisor,問佢覺得我點
warwick supervisor亦都有寫好我

而呢個oxford prof係個field係超出名,比我warwick supervisor既名氣大好多

我total報左8個program ,全部衰晒,得兩間ok

同埋oxford呢個都係msc,我本身undergrad完左先報係會著數d (以我所知唔少applicants for this program都係undergrad未grad)

如果唔係咁岩我supervisor同oxford個邊有d渊源我肯定oxford唔收
