Confidence levels for the Social and Behavioral Sciences
DARPA recently put out an RFI:
…requesting information on new ideas and approaches for creating (semi)automated capabilities to assign ‘Confidence Levels’ to specific studies, claims, hypotheses, conclusions, models, and/or theories found in social and behavioral science research (and) help experts and non-experts separate scientific wheat from wrongheaded chaff using machine reading, natural language processing, automated meta-analyses, statistics-checking algorithms, sentiment analytics, crowdsourcing tools, data sharing and archiving platforms, network analytics, etc.
A visionary and high value RFI. Wired article on the same, enticingly titled, DARPA Wants to Build a BS Detector for Science.
Claude Berrou on turbo codes and informational neuroscience
Fascinating short interview with Claude Berrou, a French computer and electronics engineer who has done important work on turbo codes for telecom transmissions and is now working on informational neuroscience. Berrou describes his work through the lens of information and graph theory:
My starting point is still information, but this time in the brain. The human cerebral cortex can be compared to a graph, with billions of nodes and thousands of billions of edges. There are specific modules, and between the modules are lines of communication. I am convinced that the mental information, carried by the cortex, is binary. Conventional theories hypothesize that information is stored by the synaptic weights, the weights on the edges of the graph. I propose a different hypothesis. In my opinion, there is too much noise in the brain; it is too fragile, inconsistent, and unstable; pieces of information cannot be carried by weights, but rather by assemblies of nodes. These nodes form a clique, in the geometric sense of the word, meaning they are all connected two by two. This becomes digital information…
Thermodynamics in far-from-equilibrium systems
I’m a sucker for methods to try to understand and explain complex systems such as this story by Quanta (the publishing arm of the Simons Foundation — as in Jim Simons or Renaissance Technologies fame) of Jeremy England, a young MIT associate professor, using non-equilibrium statistical mechanics to poke at the origins of life.
And finally, check out this neat little game theory simulator which explores how trust develops in society. It’s a really sweet little application with fun interactive graphics framed around the historical 1914 No Man’s Land Ceasefire.
