Facebook Building Major Artificial Intelligence System To Understand Who We Are Meaningful artificial intelligence has been the aim of computer science since Alan Turing first imagined, in the 1950s, a computer that “passed” as human. Hollywood movies began shortly thereafter to depict computers with human-like intelligence. But, like so many things, artificial intelligence has been much harder to achieve in reality than in the movies. But following research breakthroughs about five years ago, leading tech companies, including Microsoft, IBM and Google, have begun investing big money in artificial intelligence applications. Facebook, not wanting to be left behind, is flexing its muscles, too. Much of Wall Street’s interest in Facebook, albeit fickle, has stemmed from the potential commercial value of what the social network knows about its users. And Facebook has a lot of data from which an artificial learning setup could draw inferences. “If you feed all this information, the computer is basically going to develop the ability to make sense of the inputs.
Trial of Alzheimer’s Vaccine is Successful By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on June 8, 2012 Swedish researchers report the successful trial of a vaccine that helps individuals develop protective antibodies that can prevent progression of Alzheimer’s disease. Alzheimer’s is a neurological dementia disease in which the body attacks itself destroying brain cells. The prevailing hypothesis about the origin of Alzheimer’s involves APP (amyloid precursor protein), a protein that resides in the outer membrane of nerve cells. There is currently no cure for Alzheimer’s disease, and the medicines in use can only mitigate the symptoms. The first human vaccination study, which was done almost a decade ago, revealed too many adverse reactions and was discontinued. The new treatment, which is presented in Lancet Neurology, involves active immunization, using a type of vaccine designed to trigger the body’s immune defense against beta-amyloid.

Wolfram|Alpha publie une étude sur Facebook Jeudi 25 avril Réseaux sociaux - 25 avril 2013 :: 07:07 :: Par Kevin Les équipes du moteur de recherche Wolfram|Alpha viennent de publier un premier rapport d’une étude qu’ils ont entreprise il y a quelques semaines : analyser le compte Facebook d’un grand nombre d’internautes pour ensuite dresser le portrait de l’utilisateur moyen. C’est par le biais d’une note de blog que le célèbre moteur de recherche scientifique a dévoilé hier un premier aperçu de son programme « Donneurs de données » (Data Donor program). WolframAlpha a lancé en août dernier un outil appelé « Wolfram Alpha Personal Analytics for Facebook », grâce auquel il est possible d’analyser en profondeur son compte Facebook. La collecte de données permet ensuite au service de classer ces informations et de mettre en forme un joli récapitulatif de ses différentes amitiés et de son activité sur le réseau social. Ces quelques graphiques, à l’instar de Wolfram|Alpha en général, se veulent scientifiques.

How Your Facebook Profile Reveals More About Your Personality Than You Know Words most commonly used by women. The researchers could predict users’ genders with 92 percent accuracy. What do your status updates really say about you? In a study published last week at PLOS ONE, scientists at the University of Pennsylvania examined the language used in 75,000 Facebook profiles. The researchers found that they could predict a user’s gender with 92 percent accuracy. To date, this is the largest study of its kind. “Automatically clustering words into coherent topics allows one to potentially discover categories that might not have been anticipated,” the authors wrote. The group was particularly interested in using this approach to determine users’ characteristics. Some of the language was consistent with previous psychological findings. But other discoveries were more novel. The researchers hope to use their findings to provide more insight into what behavior sets different types of people apart.
What Thomas Kuhn Really Thought about Scientific “Truth” | Cross-Check In 1991, when I was a staff writer for Scientific American, I wrote a letter to Thomas Kuhn, then at MIT. I said I wanted to profile him for Scientific American and “tell readers how you developed your views of the process of science.” When he didn’t respond, I called. Kuhn was reluctant to do the interview. I finally wore Kuhn down, and in February 1991 I interviewed him for more than three hours in his cluttered office. To commemorate the 50th anniversary of Structure, I’m posting an edited version of my write-up of Kuhn in The End of Science (Addison Wesley, 1996), which draws heavily on my meeting with him. The Structure of Thomas Kuhn “Look,” Thomas Kuhn said. “The book” was The Structure of Scientific Revolutions, which may be the most influential treatise ever written on how science does (or does not) proceed. Given this theme, one might think that Kuhn would have expected his own message to be at least partially misunderstood. But isn’t mathematics a kind of universal language?
La réalité détournée grâce à un iPhone Un iPhone, une image choisie au préalable et un environnement : les ingrédients simple du projet photographe d’un Français, François Dourlen. Se servir de paysages ou de situations pour mieux les détourner, voilà le curieux hobby de François Dourlen. Et une bonne partie de la Toile commence à partager ses montages qu’il veut inscrits dans le quotidien. Un cimetière ? Un zombie s’accroche à une tombe, les yeux injectés de sang. Un bateau échoué sur la plage ? Comme il le précise au Huffington Post, son processus photographique est simple : Je charge l’image sur mon téléphone, j’essaie de la faire coïncider avec la réalité et je prends la photo avec mon appareil reflex. Rien de nouveau sous le soleil Pour autant, cet engouement pour François Dourlen est à prendre avec des pincettes. Il y a quelques mois, le travail du journaliste canadien Christopher Moloney, émigré à New York, faisait parler de lui. Ici, un exemple avec S.O.S. S.O.S. On vous conseille également :

Back to Basics: Four (Free) Online Psychology Courses I live in a college town. In fact, I live in the college town in which I used to attend college. I moved back here a few months ago and I pass my (er, the college’s) library daily. It brings back plenty of academic memories — and, surprisingly, they’re not the stressful ones. But the positive stuff remains: the nights spent in a library study nook with my Intro to Communication textbook and a highlighter. The satisfaction of applying a concept I learned in my 9 a.m. The scent of the pages of a brand-new textbook. I hit the peak of wistful sentimentality last week and found a way to re-create a portion of the academic college experience (without the stress!) Go ahead. 4 Free Online Psychology Courses There are dozens (if not hundreds) of free online courses from major universities like Yale and MIT. And lucky for us lovers of all things psychology, there are four complete psychology courses to choose from: I’m about a third of the way through Dr. What do your dreams mean? Dr.
À Stockholm, le métro c’est tout un art | WhoTheFuckAreYou A Stockholm, le musée d’art le moins cher se trouve sous terre et il coûte le prix d’un ticket de métro. Ah, le métro ! Sa vieille odeur, ses courants d’air, ses gens qui font la gueule… Drôle d’idée que de se dire que dans la capitale suédoise, il est non seulement un moyen de transport mais aussi une des attractions de la ville : 90 des 100 stations de la ville sont des œuvres d’art. Une manière de joindre l’utile à l’agréable (l’agréable à l’utile plutôt). Inauguré en 1950, ce n’est que quelques années plus tard que les travaux artistiques vont commencer. Peintures, sculptures, mosaïques, reliefs ornent le sol et les murs et des visites guidées sont même organisées. Rating: 10.0/10 (6 votes cast) À Stockholm, le métro c'est tout un art, 10.0 out of 10 based on 6 ratings
Social media more complex than great literature - Idibon The Washington Post recently published an article about online/offline reading differences. Are our reading abilities changing? “They cannot read ‘Middlemarch.’ So this post tries to answer the question: Is social media harder or easier to read than Henry James and George Eliot? Now to refresh your memory, here’s the opening of George Eliot’s Middlemarch: Who that cares much to know the history of man, and how the mysterious mixture behaves under the varying experiments of Time, has not dwelt, at least briefly, on the life of Saint Theresa, has not smiled with some gentleness at the thought of the little girl walking forth one morning hand-in-hand with her still smaller brother, to go and seek martyrdom in the country of the Moors? I mean, just yesterday. A dirty secret of computational linguistics is similar to the WaPo article: “syntax is dead”. But that doesn’t mean there isn’t a lot of insight to gain from thinking syntactically. 124 was spiteful. How do you make a great beginning?
