Introduction: Great anti-pop-science article of the moment — Mark Liberman does a take-down of David Brooks’ apparently careless column on cultural psych experiments that purport to show that East Asians are collectivist while Westerns are individualist. From Liberman: Question to Language Log: Is it correct that if you show an American an image of a fish tank, the American will usually describe the biggest fish in the tank and what it is doing, while if you ask a Chinese person to describe a fish tank, the Chinese will usually describe the context in which the fish swim? Answer: In principle, yes. But first of all, it wasn’t a representative sample of Americans, it was undergraduates in a psychology course at the University of Michigan; and second, it wasn’t Chinese, it was undergraduates in a psychology course at Kyoto University in Japan; and third, it wasn’t a fish tank, it was 10 20-second animated vignettes of underwater scenes; and fourth, the Americans didn’t mention the “foca

Introduction: This is a fun one: researchers trained capuchin monkeys to understand tokens as currency by letting them exchange them for food. Then they did all sorts of behavioral economics-y tests like finding consistency of preferences revealed in price shocks. The monkeys even displayed loss aversion at rates almost identical to humans! And along the way they got “prostitution”: Something else happened during that chaotic scene, something that convinced Chen of the monkeys’ true grasp of money. Perhaps the most distinguishing characteristic of money, after all, is its fungibility, the fact that it can be used to buy not just food but anything. During the chaos in the monkey cage, Chen saw something out of the corner of his eye that he would later try to play down but in his heart of hearts he knew to be true. What he witnessed was probably the first observed exchange of money for sex in the history of monkeykind. (Further proof that the monkeys truly understood money: the monkey who

Introduction: I got an email from a promoter for Predictive Analytics World , a very expensive conference next month in San Francisco for business applications of data mining / machine learning / predictive analytics. I’m not going because I don’t want to spend $1600 of my own money, but it looks like it has a good lineup and all (Andreas Weigend, Netflix BellKor folks, case studies from interesting companies like Linden Labs, etc.). If you’re a cs/statistics person and want a job, this is probably a good place to meet people. If you’re a businessman and want to hire one, this is probably a bad event since it’s too damn expensive for grad school types. I am supposed to have access to a promotional code for a 15% discount, so email me if you want such a thing. John Langford posted a very interesting email interview with one of the organizers for the event, about how machine learning gets applied in the real world. The guy seemed to think that data integration — getting all the data out of d

Introduction: Playing around with stream.twitter.com/spritzer , ggplot2 and maps / mapdata : I think I like the top better, without the map lines, like those night satellite photos : pointwise ghosts of high-end human economic development. This data is a fairly extreme sample of convenience: I’m only looking at tweets posted by certain types of iPhone clients, because they conveniently report exact gps-derived latitude/longitude numbers. ( search.twitter.com has geographic proximity operators — which are very cool! — but they seem to usually use zip codes or other user information that’s not available in the per-tweet API data.) So there’s only 30,000 messages out of 1.2 million spritzer tweets over ~3 days (itself only a small single-digit percentage sample of twitter).
3 0.52510816 154 brendan oconnor ai-2009-09-10-Don’t MAWK AWK – the fastest and most elegant big data munging language!
Introduction: update 2012-10-25 : I’ve been informed there is a new maintainer for Mawk, who has probably fixed the bugs I’ve been seeing. From: Gert Hulselmans [The bugs you have found are] indeed true with mawk v1.3.3 which comes standard with Debian/Ubuntu. This version is almost not developed the last 10 years. I now already use mawk v1.3.4 maintained by another developer (Thomas E. Dickey) for more than a year on huge datafiles (sometimes several GB). The problems/wrong results I had with mawk v1.3.3 sometimes are gone. In his version, normally all open/known bugs are fixed. This version can be downloaded from: http://invisible-island.net/mawk/ update 2010-04-30 : I have since found large datasets where mawk is buggy and gives the wrong result. nawk seems safe. When one of these newfangled “Big Data” sets comes your way, the very first thing you have to do is data munging: shuffling around file formats, renaming fields and the like. Once you’re dealing with hun

Introduction: This is fascinating — In China, you can get fined if you make a map of China without Taiwan or other disputed territories . Reminds me of being confused trying to find the primary airline of China. Based of vague recollections of its name, I searched Google for {{ china air }} . The first hit was for China Airlines . But the second hit was Air China . The first is the state carrier of the ROC (Taiwan), the second is the PRC (mainland China). Turns out my intended concept, “Official Chinese airline”, isn’t a coherent concept if your political worldview includes both the ROC and PRC as entities. But maybe what I should have wanted was just airlines that fly around East Asia and various parts of China; in that case, getting both airlines is the right thing to do. At least Google got them both at the top of the list. (p.s. anyone know how to force blogger to *not* destructively resize your images? sigh)

Introduction: Great anti-pop-science article of the moment — Mark Liberman does a take-down of David Brooks’ apparently careless column on cultural psych experiments that purport to show that East Asians are collectivist while Westerns are individualist. From Liberman: Question to Language Log: Is it correct that if you show an American an image of a fish tank, the American will usually describe the biggest fish in the tank and what it is doing, while if you ask a Chinese person to describe a fish tank, the Chinese will usually describe the context in which the fish swim? Answer: In principle, yes. But first of all, it wasn’t a representative sample of Americans, it was undergraduates in a psychology course at the University of Michigan; and second, it wasn’t Chinese, it was undergraduates in a psychology course at Kyoto University in Japan; and third, it wasn’t a fish tank, it was 10 20-second animated vignettes of underwater scenes; and fourth, the Americans didn’t mention the “foca
