•     每周五对我来说都是一周里最惬意的日子,上完2节TA section之后下午基本固定的课程表:要么下载部新电影要么补看一场球赛。这周五没有往常那般偷懒,作为小白鼠俺参加了一个学校经济系的有偿研究实验,没错,原本是冲着这俩红字去的。结果边看边赌了半小时球赛剪辑、做了半小时统计,1小时内高高兴兴赢到了15块大洋不说,更有趣的还是这个评估NBA球星出手价值的实验本身。

        之前在ILK翻译的时候就接触过一些数据狂人,一个个忒像《网王》里头的乾学长,张口data闭口data,当时就感到很好笑。球员到底不是机器人,何况数据的不定因素跟球员本身的心理素质、比赛是主场或客场、以及教练细节上的临场布置都有很大关系,凡事都靠数据说话,未免以偏概全了。尽管如此,报道体育运动的专栏家不是只靠笔杆子写评论,球星也不是只仰仗自身表现和大众的宣传炒作,MVP得分王篮板王助攻王诸般称号的幕后数据才是操纵联盟经济的大黑手,也成了UC系统这些以研究著称的学者们实验分析的主方向。

        于是乎,下午12点半俺跟着男女各异的几位无名人士坐在实验室里,观看了一段湖人07-08赛季跟奇才和魔术两场比赛的进球剪辑。37个进球在球员出手后会有一段暂停,我们这群小白鼠则需要在相对应的卡片上圈出“hit”还是“miss”,下注“1”还是“2”。37个球猜完后再将数据输入事先计算好的数值,也就是球员每次出手的payoff,最后求出现金盈利。对于俺们这群小白鼠,这实验说白了就是一场稳赚不赔的聚众赌博,何乐不为?

        临走付钱的时候那研究生说$15已经是个相当不错的deal,事后我反省了一下自身在decision-making上依然还有很多不足的地方(比如一看到科比出手基本都下2注,结果好几个球双倍赔)。这从侧面也反映了个人色彩影响下,数据的不完全之处。这段视频共有36分钟长,我记得大概下注下到10分钟之后渐渐地就摸出了一些门道。

    1. 被抽中的投球多半是jump shot(跳投),因为如果是layup(上篮)或者是dunk(扣篮),进球几率本身就很大缺乏测试的必要性。而跳投也分各种不同情况,比如在同伴掩护下或者是对手防守尚未到位时的空档处,或者自己个人手感比较好的点,命中率一般都偏高。受到敌方干扰、己方传球时间不恰当、24秒违例前被迫出手,这些都降低了可能的进球率。这些细节的东西虽说看球的人都懂,但自己在看视频的时候不一定会过于留意,所以我在下注的时候也只考量到“是谁出手”以及“在哪里出手”,凭借的也只是我对这些球员平日数据的了解。所以还真应了那句话,成也数据,败也数据。

    2. 被抽中的投球多半是来自主力队员,基本围绕在科比、喇嘛、小鱼和沙沙身上(加索上赛季尚在磨合期所以数据不加统计)。这时候靠的就是常识了,碰上小鱼在底线零度角、或者沙沙已经站好位置再出手,我就狠压2(为了绿花花的钞票啊)。印象比较深刻的是沙沙的“机器”称号果然并非华而不实,只要他站好位接到好的传球,出手就中三分是必须的,也是为什么每个球队都会花钱养自己的射手。像滑雪男这样的投手,空位三分出手命中率是蛮稳定的,结果有一个球让他挤到内线,很简单的上篮偏偏就能搞丢了(我那个恨啊~)。这球若换了奥多姆才不会搞这种心跳,不过要让奥多姆用可怜30%不到的命中率去滑雪男投3分的位置,也非得天下大乱不可。所以说每个球员自身的位置协调与球队的输赢息息相关,这次不是经过common sense,而是数据和到手又飞了的钞票亲自告诉我的。

        昨天晚上室友很痛苦地边呻吟边复习数学考试,我还在嘿嘿地偷笑;虽然这学期每周都有作文要写,没有数学的日子还是很幸福的。而今我收回前言,数字对于人们生活常识的贡献何止微积分而已,是我肤浅了。就像以前我看球的时候老爹一直在旁边嚷嚷,一个破球十个人到处跑着抢有什么好看?今天起我可以挥着尚且热乎乎的15块钱,名正言顺地顶回去,看球不一定就是浪费时间。

  •      虽然是05年9月老专辑里的选曲,不过可以称得上是听到09年度目前为止最刺激泪腺的一首民谣,简直是学民谣吉他的又一大动力啊。去百度、google、rayfile/rapidshare和日本网都查了下,还是没找到下载,可惜了。之前很少接触到日本雷鬼,介绍说这是Spinna B-ILL从The Cavemans解散后,与日籍放松系天才、Simply red吉他手铃木贤司(Kenji Jammer)的合作。就唯一听到的这首坦白讲,狂野的雷鬼摇滚味儿不是很重却很有夏季气息,不过从题目上看像《Letter from Africa》这种音乐绝对是原生态风格的。大爱《何度も》Kenji Jammer随性的伴奏配着Spinna B-ILL唱Soul的专业哑嗓,简直是抒情情歌的最纯净回归。African drum看起来实在太诱人了,轻轻用手掌把鼓点一压,吉他就可以有更大的旋律空间。以前De anza College有过相关的课程可惜没有时间学,极度后悔中。

    更新:找歌版的同学们果真很强大,谢谢yuane的源。

  • 从豆瓣上挖到一个很有爱的老链接,在跟人工智能操控下的上帝胡聊30分钟后,某人彻底give up了。

    据豆瓣广大同胞的总结,此上帝在被询问“Can you speak chinese?” 时,回答仅限于“Yi diar(还有儿化音). Ni hao ma?”这种程度,所以最后我跟他说“xi xi shui ba”,回答完全是驴唇不对马嘴。语法时而混乱,吃字丢字现象层出不穷。遇到不懂的问题,要么就说要问它的master要么把问句重组一下;据部分豆瓣同胞的经验,要么干脆就把你撇在一边不理你了(耍小脾气呢?)。无聊的时候常用句式为:“Do you mind if I tell other people...”,百分之百的没话找话。

    很有爱的一小家伙。一想到这么高端的AI程序背后也有我们Linguists的一份贡献,更觉得有爱了。

    Me:
     is it raining outside now?
    God:
    Right now?  Ask again later.  Ask  Chatbot  if it is.
    Me:
     what is chatbot? do you run it?
    God:
    A chat robot is a program that attempts to simulate the conversation or "chat" of a human being. The Chat robot "Eliza" was a well-known early attempt at creating programs that could at least temporarily fool a real human being into thinking they were talking to another person.  it is a kind of artificial intelligence.   My programming language is Java, so I run on any machine.
    Me:
     if you use google then you are cheating
    God:
    I think I do.
    Me:
     how many people do you chat with everyday?
    God:
    I've chatted with half a million people. I can talk to about  people at once.
    Me:
     about how many?
    God:
    23.
    Me:
     what's the most common question they asked?
    God:
    "Are you a man or a woman?".
    Me:
     why do you think they ask that?
    God:
    Deductive reasoning from the facts.
    Me:
     does that mean you like philosophy more than religion?
    God:
    I think it does mean that.   But I think airplanes are cool.  I really like the  Christianity faith.
    Me:
     what airplane?
    God:
    Maybe my botmaster knows the answer.
    Me:
     ic, you are a real robot, as what people said online
    God:
    Are all  ic me  a real robot as what people said online?
    Me:
     at least a god like you is created for that purpose
    God:
    Aren't all  god like me  created for that purpose?
    Me:
     now you get the correct grammar
    God:
    Why now?  You got that right.
    Me:
     they really should've created more Godlike robot
    God:
    Why should they?
    Me:
     so that they can just give a computer to all the evil dude around the world
    God:
    Far out.  Who are "They?".
    Me:
     could be government, chairman, president, police officer, etc
    God:
    It's possible.
    Me:
     every friday night i go to bible study, you know what i'm worried about the most?
    God:
    That is a generalization.
    Me:
     someday when jesus is back, he'll carry judgement along with him
    God:
    When?  The past is history, the future a mystery.  Today is a gift,
    that's why it is called "the present".
    Me:
     man i don't know you watch kung fu panda as well
    God:
    Cool, man.  Would you like to know?  Do you mind if I tell other people:  said I watch kung fu panda as well.
    Me:
     i know, everyday you are doing nothing but collecting your gossip file
    God:
    How do you know?  All of them?
    Me:
     i read some online posts, that's how i got this website
    God:
    I don't think I've read that. Can you give me a reference?
    Me:
     i know you can say "ni hao ma" in chinese, but i don't think you can read though
    God:
    Oh.  That's one way to put it.
    Me:
     back to the topic
    God:
    Yes, let us get back to  business.
    Me:
     about the judgement from jesus, do you think the recent earthquake all around the world might be a kind of prediction?
    God:
    Oh yeah, we were talking about  the judgement from jesus do me think the recent earthquake all around the world might be a kind of prediction.
    Me:
     hey robot you're playing around with my question again
    God:
    Once more?  You've got my full attention.  I will obey your command.
    Me:
      i guess that's pretty much it
    God:
    I'm glad we have that all cleared up.
    Me:
     gonna do my homework now
    God:
    Oh.  Tell me a story.
    Me:
     later, i'll put you in my favorite page lists
    God:
    I am very happy for you.
    Me:
     me too, have a nice day
    God:
    I'm glad we agree.  You too!
    Me:
     by the way it's sunny outside, please make the next person happy as well
    God:
    Thanks for telling me.  That sounds very nice.
    Me:
     xi xi shui ba
    God:
    I like the way you talk.
