C'est La Vie

Flowing Data 有個很有趣的單元 Data Underload,用 Google 搜尋某個【句子+特定關鍵字】的筆數結果製成圖表,結果常令人發噱。雖然有些數字和經驗與常識所得的揣測相符,有時可未必如此,但有時結果和親手驗證的結果未必相符,就不知是怎麼回事了?

今日(2010/03/29)的主題:Life is like + ???,拜電影阿甘正傳之賜,人生就像一盒巧克力(life is like a box of chocolate)的結果僅次於人生就是那麼回事啦(life is like that)!這個答案很精彩,很有點洞燭世情的滄桑味道,讓人不由得不信。但是我自己動手查詢 life is like a book 的結果,卻遠遠超過這張圖的數字?



看完上面這張圖,一時手癢,做了一份中文版【人生就像 + ???】,結果不算意外,大家都覺得人生就像一首歌!?

15 Petabytes a day makes a smarter planet ?

這個月初整理 How big is Digital Universe 的相關數據, 令人乍舌的數字充分顯示:人類製造資訊的能力和產出垃圾的能力一樣高明(呃,資訊 = 垃圾?)。就個人而言,如何在資訊洪流裡面,如何篩選有用的訊息,少做無用之功,是現在人必修的功課;對群體而言,如何利用科技,充分開發資料的價值,是研究人員的艱巨挑戰。IBM 力推的智慧星球(Smarter Planet)計畫,顯然對科技的力量有正面樂觀的期許:

Daniel Lemier's advice on How to Write Good Papers

Daniel Lemire 是我很敬佩的一位學者,他在推薦系統領域知名度相當高,而且是學術界投入部落格書寫的先行者之一。他的部落格並不局限於推薦系統議題,還涉及演算法和資訊科學理論的基礎問題,他還不時以自身的經驗提供出如何做研究、寫論文的建議,文章品質都很棒。昨日 Daniel Lemire 在 SlideShare 放上他針對研究生演講(talk?)如何撰寫論文的簡報,看了簡報,我只有一個想法,我實在是太混了。

[PDF] How to read a research paper

哈佛大學教授 Michael Mitzenmacher (部落格 My Biased Coin 的作者)提供一份很棒的如何閱讀論文 (下載電子檔) 的指引和建議,並且願意提供原稿(他是用 Latex 寫的),讓大家繼續發揚改進。Mitzenmacher 教授在他的部落格還特別推薦Jason EisnerHow to Read a Technical Paper 的最後一節 What to read



What to read

  • creative web search



    • experiment with several searches
    • put yourself in an author's shoes; what phrases might they have used?
    • become a power searcher! (read the help pages for your search engine) 

  • find related work



    • backward references: follow the bibliography to earlier papers
    • forward references: see who else has cited the work (via an interface such as Google Scholar




    • has someone else already listed the right papers for you?



      • survey papers in journals (also called "review articles")
      • course syllabi
      • reading group webpages
      • chapters in textbooks
      • online tutorials
      • literature review chapters from dissertations
      • direct recommendations from friends or professors (perhaps at other institutions) 




      • breadth-first exploration



        • read a lot of abstracts (and skim the papers as needed) before deciding which papers are best to read
        • it's okay to read multiple related papers at once, flipping back and forth so that they clarify one another
        • to get a feel for the research landscape in an area, flip through the proceedings of a relevant recent workshop, conference, or special-theme journal issue 




        • when the going gets tough, switch to background reading



          • textbooks or tutorials
          • review articles
          • introductions and lit review chapters from dissertations
          • early papers that are heavily cited
          • sometimes Wikipedia

        [Video] Nature by Numbers

        我想大家應該都同意數學是科學之母,其實數學無處不在,在我們身邊的大自然裡,在我們伸手可及的生活裡。一個老外 Cristóbal Vila 製作了一個短片,把自然界裡可見的數字和幾何現象,做了很棒的呈現:

        如果我的心是一朵蓮花

        ~ 林徽因 · 馬雁散文集 · 蓮燈 ~ 馬雁 在她的散文《高貴一種,有詩為證》裡,提到「十多年前,還不知道林女士的八卦及成就前,在期刊上讀到別人引用的《蓮燈》」 覺得非常喜歡,比之卞之琳、徐志摩,別說是毫不遜色,簡直是勝出一籌。前面的韻腳和平仄的處理顯然高於戴...
