The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]
Mario AI - "Mario's inner emotive states cause behavior-determining drives. For example, Mario will collect coins if he is hungry. Whereas, when he is curious, he will explore his environment and autonomously gather knowledge about items he does not know about yet."

Peter Turchin is a Professor of Mathematics, and of Ecology and Evolutionary Biology at the University of Connecticut. For the last nine years, he's been taking the mathematical techniques that once allowed him to track predator–prey cycles in forest ecosystems, and using them to model human history -- a pattern identification process he calls Cliodynamics. The goal of cliodynamics (or cliometrics) is to turn history into a predictive, analytic science. By analysing some of the broad social forces that shape transformative events in US society: historical records on economic activity, demographic trends and outbursts of violence, he has come to the conclusion that a new wave of internal strife is already on its way, and should peak around 2020.

The scholarly literature forms a vast network of academic papers connected to one another by citations in bibliographies and footnotes. The structure of this network reflects millions of decisions by individual scholars about which papers are important and relevant to their own work. Therefore within the structure of this network is a wealth of information about the relative influence of individual journals, and also about the patterns of relations among academic disciplines. Our aim at eigenfactor.org is develop ways of extracting this information. [more inside]
