Does the internet actually inhibit, not encourage democracy? In this new RSA Animate adapted from a talk given in 2009, Evgeny Morozov presents an alternative take on 'cyber-utopianism' - the seductive idea that the internet plays a largely emancipatory role in global politics.
Exposing some idealistic myths about freedom and technology (during Iran's 'twitter revolution' fewer than 20,000 Twitter users actually took part), Evgeny argues for some realism about the actual uses and abuses of the internet
Richard Feynman, Winner of the 1965 Nobel Prize in Physics, gives us an insightful lecture about computer heuristics: how computers work, how they file information, how they handle data, how they use their information in allocated processing in a finite amount of time to solve problems and how they actually compute values of interest to human beings. These topics are essential in the study of what processes reduce the amount of work done in solving a particular problem in computers, giving them speeds of solving problems that can outmatch humans in certain fields but which have not yet reached the complexity of human driven intelligence. The question if human thought is a series of fixed processes that could be, in principle, imitated by a computer is a major theme of this lecture and, in Feynman's trademark style of teaching, gives us clear and yet very powerful answers for this field which has gone on to consume so much of our lives today. No doubt this lecture will be of crucial interest to anyone who has ever wondered about the process of human or machine thinking and if a synthesis between the two can be made without violating logic.
Spotify uses a range of large scale machine learning methods to find interesting music recommendations. Using large amounts of implicit data, collaborative filtering is behind features such as radio, related artists, and a number of soon to be released features. These are powered by matrix factorization and other methods that have been scaled up to 100s of billions of data points.
