Data Science of the Facebook World—Stephen Wolfram Blog

Data Science of the Facebook World—Stephen Wolfram Blog
More than a million people have now used our Wolfram|Alpha Personal Analytics for Facebook. And as part of our latest update, in addition to collecting some anonymized statistics, we launched a Data Donor program that allows people to contribute detailed data to us for research purposes. A few weeks ago we decided to start analyzing all this data. And I have to say that if nothing else it’s been a terrific example of the power of Mathematica and the Wolfram Language for doing data science. (It’ll also be good fodder for the Data Science course I’m starting to create.) We’d always planned to use the data we collect to enhance our Personal Analytics system. I’ve always been interested in people and the trajectories of their lives. So what does the data look like? So a first quantitative question to ask is: How big are these networks usually? But how typical are our users? So, OK. But what friends do they add? And here’s an interactive version, generated from CDF: OK. But, OK.

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.

List of mathematical symbols When reading the list, it is important to recognize that a mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations a different convention may be used. For example, depending on context, the triple bar "≡" may represent congruence or a definition. I need the men’s rights movement because.. Early in 2012, a feminist campaign emerged online which included a series of photographs. Each picture was of a young man or woman, presumably students at university and college. Each young man or women holding a sign which began with “I need feminism because..” The reasons following these declarations were varied, and mostly incoherent.

VC 100: The Top Investors in Early-Stage Startups Welcome to the Entrepreneur VC 100 list of top early-stage venture capital firms -- a platform highlighting the who’s who of the U.S. startup ecosystem. The ranking is based on data from PitchBook, a Seattle-based data and tech provider for the global private equity and venture capital markets. The firms are listed by total capital invested in seed and/or early-stage deals completed in the U.S. during 2014. While the ranking is focused on traditional VC firms, it also includes corporate VCs, mutual funds and other entities, as new players increasingly enter the VC game. 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.

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.’ They cannot read William James or Henry James,” Wolf said.

Classic intra-frame prediction is one example of a Catch-22 caused by lapping: We can't predict from neighboring pixels that have not yet been fully decoded, and we can't finish decoding these pixels until we lap them with the current block, which of course can't be decoded until after prediction. To unravel this circular dependency, Daala predicts from neighboring frequency coefficients rather than neighboring pixels. This strategy also makes use of a larger amount of prediction information, as it predicts from several full blocks of coefficients, rather than a thin strip only one or two pixels wide. Above: Dr.
