Is the future of surgery robotic?

Surgery is a field that requires a lot of focus and precision. Indeed, there can be no mistakes in surgical operating rooms and surgeons can use all the help they can get. This is where surgical robots come into play. Perhaps the most famous surgical robot is the Da Vinci robot. That mac

Verónica Becher: Independence of normal words

Abstract : Recall that normality is a elementary form of randomness: an infinite word is normal to a given alphabet if all blocks of symbols of the same length occur in the word with the same asymptotic frequency. We consider a notion of independence on pairs of infinite words formalising

Speaker: Sergey Although most academics and industry practitioners regard "hacking" as mostly ad-hoc, a loose collection of useful tricks essentially random in nature, I will argue that hacking has in fact become a "distinct research and engineering discipline" with deep underlying engine

ElixirConf 2015 - The road to intellij-elixir 1.0.0 By Luke Imhoff

Learn how naively copying a grammar file from one parser generator to another won't work. Go back to the beginning and learn about lexers vs parsers, but discover that the power of interpolation changes the computational complexity and forces the lexer to be a push-down automata instead of

Recurrent Neural Networks and Models of Computation - Edward Grefenstette, DeepMind

This talk presents an analysis of various recurrent neural network architectures in terms of traditional models of computation. It makes the case for simpler recurrent architectures being closer to finite state automata, and argues that memory-enhanced architectures support better algorith
