其實點為之學好咗一個language

可以用coq proof 個隻language 的soundness & completeness


閣下up乜春? 駛唔駛學埋OCaml(coq is written in OCaml)?

proof type system sound and complete


A system is sound, if it never accepts a false positive program.
A system is complete, if it never accepts a false negative program.

學埋啲language野

讀好啲數

出黎做NLP, computer vision, robotics, machine learning, FG都有2X-3Xk

Ml好高要求wor清


係囉, 連登仔個個都有十個八個PhD既實力, 可以當ML係小兒科咁!
(我讀過Stat去到MANOVA既程度都唔敢掂ML! )

都有啲低水準啲的ML,冇人叫你下下做Deep NN

啲fiance sector的modeling 其實都好好pay

巴打做呢行?

唔係做ml,不過識有人數學勁,讀完個土木master去做modelling

Coq只係tools,當然你可以用紙筆proof

Proof到代表你了解個language的type system

OK.

BTW, 居然有人用mathematical proof既角度去話咁為之學好咗一個language? It's so funny but interesting!

咁冇勁數底[分分鐘可能要PhD級]又做唔到coq proof既人就千祈唔好話自己master咗一個programming language, 至少唔好係你面前, 係咪呢?!

仲有, 如果你老板/上司有日同你講唔L識呢D, 而你又係developer既話, 你係咪會覺得佢地冇L用, 打錯咗呢份工呢?!

city cs好定poly computing好?


CU CS 好

加埋hku 同Ust 又邊個好

Ust 教既野唔會差好遠 但係好chur 好爛grade
但係啲ust resources 好啲 啲assignment lab 學到好多野 prof 同ta 好有心去design

HKU CS 唔多好, 仲都好多入ibank
我之前係ASSO 升入U, 有UST同CU CS offer
我最後入左CU, 因為我鐘意CU 個 culture, alumni network 夠大, college, reputation
但我覺得UST 既CS 好D.. D 學生認真D, international D
但都係睇你自己主唔主動, 同埋鐘唔鐘意

唔好俾D人成日話UST chur呃左
CU/UST CS workload其實差唔多(一樣chur)
至於學生認真 我相信ust比例 比 CU高唔少,但如果你識班認真讀書既同學一齊上堂應該冇咩分別
international答你唔到
至於老細睇CU/UST幾乎一樣,睇人多過睇學校

利申:舊年CU fg,同個ust cs fd一齊讀

我可能識你 haha
For CS, CU = UST > HKU,


其實點解?

利申 排第三嗰間

老土啲講句
學什麼web, mobile呀其實都係update得好快既野
js既framework日日有新
swift123直情係三隻唔同既lauguage
所以讀得多呢啲freah grad一定易搵到工
但會好快被淘汰(原因同當初請你既一樣)

但打好algo, data structure, OS, principle of pro lang既底
首先呢啲野好少變
另外就係會幫到你學新language同framework

巴打不太了解數撚既特性
數撚大部份時間只關注true false existence uniqueness既四個問題
至於個 helloworld點打……
我證明到一個打得出 helloworld 既program存在咪得囉

利申 讀CS 半個數撚(minor math)

大學既CS 其實好有用
concept 通常係冇咁短命
反而language, framework, 甚至programmimg practices 都係會轉得好快

唔好expect 自己識哂主流既野
10間公司可能會用10種唔同language唔同framework
唔好話fg, 就算你有十年經驗到你轉工時一樣都係從新pickup

我覺得大學學principal of programming language, software engineering, algorithm, database design principles, networking, 好多都終生受用
optional ge AI, web development, mobile, graphic, security, 甚至學創業, 是旦一樣都比一套某一範疇ge framework重要


睇哂成個POST,好多人都係想學practical野,覺得學theoretical 野無撚用(esp 工作上)

其實有呢種諗法既人根本唔需要讀大學,讀hd 已夠,內容夠practical,training 夠多,係咪?

大學唔等於職業訓練所,只係社會工作既一張入場卷

出左黎社會,你要再搵人上好theoretical 既 course 係好撚難(當然宜家有ocw) , 但係practical 野大把坊間course / 公仔書可以幫你pick up 番

基於呢種心態同風氣,香港需要既似乎唔係大學,而係醫學院同vocational school

睇漏咗依個,agger,有部分同學仲話想多啲practical,話出到去唔識practice,痴線。啲大公司全部睇緊你有幾多theory,仲走去學practical,有鬼用

巴打覺得data structures重唔重要

重要呀,前提係儲ge data 係有structure 同relationship,如果唔係應該用nosql

係咪搭錯咗,我估佢應該係問heap, binary tree, hashmap, graph嗰啲data structures

我唔太清楚
其實我係本來想讀data structures但reg唔到
想知自己miss左既野重唔重要

Data structure同algorithm算係cs嘅基礎
講真你揾份普通dev用得著好深嘅algo/data struct嘅機會唔多
但係一用起上黎/自己design就見真章
再簡單嘅data struct都要解釋倒佢嘅complexity俾同事聽人地先放心俾你上

啲framework呀,language呀你自學都得,但係真係係u入面(or某啲programming比賽)先會學到呢類知識
應該都冇咩人會無啦啦攞本intro to algo黎刨

另外in啲好啲嘅it工見你係undergrad好多時候會問你algo/data struct,有備無患

Truth

Stat都係熱門問題

唯有自學 reg唔到
差唔多畢業

幾年都reg唔到?咩U
我嗰間係基本上一定要讀先grad到,對入Google依類公司嘅interview幾有用

For CS, CU = UST > HKU,


其實點解?

利申 排第三嗰間

可能啲prof 唔夠另外個兩間好, 啲學生唔係好搞啲startup, 幫唔到個系出名, 同埋啲學校多數入返bank/ financial industry, 比較business, 另外個兩間啲學生好practical, 同埋啲tech skills 都好好,多數會入返啲tech 公司或者research

我都讀緊 cs 已經year 3 仲係識好少code

可以買d咩 或報d咩course 學下 先可以dup好我份fyp

已經決定左畢業出黎搵份正苦工過世算

好似得一間必修

btw 以課程嚟講,如果問點解cu 好過ust
我會覺得係cu 科 automata 係必修而其他學校唔係

人生有讀theoretical cs 先叫做讀過cs
無呢科既只係讀緊software engineering
