The Dependability of Complex Socio-technical Infrastructure & Smart Grids and Smart Meters: Game Changer, or Serious Danger? by Prof. Ross Anderson

DLS Programme Lecture 1: The Dependability of Complex Socio-technical Infrastructure Abstract: We have all become dependent on large complex systems such as Facebook, the bank payment system and even the Internet itself. Keeping these systems dependable in the face of accidents, errors and malice is one of the most important, and interesting, challenges facing engineers … The Dependability of Complex Socio-technical Infrastructure & Smart Grids and Smart Meters: Game Changer, or Serious Danger? by Prof. Ross Anderson

Learning hard chart constraints for efficient context-free parsing by Brian Roark – Oregon Health & Science University

Abstract: In this talk, I’ll present some recent work in learning hard constraints for cells within a context-free parsing chart, to reduce parsing time. Each cell in the chart represents one of the O(n^2) substrings of the input string, and characteristics of each substring can be used to decide how much work to do in … Learning hard chart constraints for efficient context-free parsing by Brian Roark – Oregon Health & Science University

Is provenance logical? (James Cheney, University of Edinburgh)

Research on provenance in databases (or other settings) sometimes has an arbitrary flavor. Once we abandon the classical semantics of queries there is a large design space for alternative semantics that could provide some useful provenance information, but there is little guidance for how to explore this space or justify or compare different proposals. Topics … Is provenance logical? (James Cheney, University of Edinburgh)
