The Endeavour

The Endeavour
I help people make decisions in the face of uncertainty. Sounds interesting. I’m a data scientist. Not sure what that means, but it sounds cool. I study machine learning. Hmm. I’m into big data. Even though each of these descriptions makes a different impression, they’re all essentially the same thing. There are distinctions. “Decision-making under uncertainty” emphasizes that you never have complete data, and yet you need to make decisions anyway. “Data science” stresses that there is more to the process of making inferences than what falls under the traditional heading of “statistics.” Despite the hype around the term data science, it’s growing on me. Machine learning, like decision theory, emphasizes the ultimate goal of doing something with data rather than creating an accurate model of the process that generates the data. “Big data” is a big can of worms. Bayesian statistics is much older than what is now sometimes called “classical” statistics.

Mathieu Agopian Le problème Hier, le 8 avril 2014, une énorme faille de sécurité a été divulguée, nom de code Heartbleed (plus d'infos sur Elle impacte OpenSSL, qui est la technologie qui permet de sécuriser les échanges entre notre navigateur et les sites qui utilisent des adresses qui commencent par " (notez bien le "s" final). On estime qu'elle impacte environ 2/3 des sites sur internet. Ces sites qui utilisent SSL apparaissent avec un petit cadenas à gauche de leur adresse, dans la barre d'adresse de votre navigateur, indiquant que la connexion est sécurisée.

Fishing in the Bay » Blog Archive » Why I am in favour of logging A colleague recently brought to me some alternative fits he had done for a paper he was writing. The alternative fits looked very strange but had been strongly suggested by a referee. He was fitting a regression model to inter-country trade data and trying to explain patterns in terms of various measures of cultural fit.

Philadelphia Software Developer “Postgres for Developers” – Notes from PGConf NYC 2014 April 8th, 2014 — Code Examples I saw a talk by one of the core Postgres developers, which showed a bunch of interesting tricks to handle business rules in Postgres specific SQL. These are all things you could find by reading the documentation, but they are interesting enough to write up examples to highlight some interesting things you can do.

Apolitically Incorrect Newsweek has a fascinating article about an archaeological site at Göbekli Tepe in Turkey that is well worth a look. The site is the oldest religious temple ever discovered. Preliminary carbon dating has determined that some of the artifacts date from 9,400 BC, which makes the place about 11,500 years old. (Which, just to be clear, is 7000 years before the Great Pyramid and 6500 years before Stonehenge.) The article further explains: Social Science Statistics Blog 28 April 2013 App Stats: Roberts, Stewart, and Tingley on "Topic models for open ended survey responses with applications to experiments" We hope you can join us this Wednesday, May 1, 2013 for the Applied Statistics Workshop.

A place for elegant solutions Impatient R Translations français: Translated by Kate Bondareva. Serbo-Croatian: Translated by Jovana Milutinovich from Geeks Education. Preface This is a tutorial (previously known as “Some hints for the R beginner”) for beginning to learn the R programming language. Ferdy Christant A few months ago I took one of the best decisions for JungleDragon in a long while: to open up parts of its operations to the community, by means of moderations tools. It has been working very well, the community is happy with it, and it eliminates the reliance on a single person. One of such moderations tool is the ability to promote a photo to the homepage.

Statistics for a changing world: Google Public Data Explorer in Labs Last year, we released a public data search feature that enables people to quickly find useful statistics in search. More recently, we expanded this service to include information from the World Bank, such as population data for every region in the world. More and more public agencies, non-profits and other organizations are looking for ways to open up their data and expand global access to this kind of information. We want to help keep that momentum going, so today we're sharing a snapshot of some of the most popular public data search topics on Google. We're also launching the Google Public Data Explorer, an experimental visualization tool in Google Labs. Popular public data topics on GoogleWe know people want to be able to find reliable data and statistics on a variety of subjects.

You can query the API with an ISBN number, and see articles about the corresponding book, or by a MusicBrainz ID, and see articles about the artist or composer. Here are some answers to frequently asked questions about this feature. Questions Answers
