Silicon Brains: Not as Cuddly as the Real Thing.

by Dr. Jekyll in Lunatic Laboratories

Are you real? What is ‘real’, more of a philosophy question than a scientific one, but what if a computer worked like your brain? What if, one day the line […]... Read more »

Cross-validation in finance, psychology, and political science

by Artem Kaznatcheev in Evolutionary Games Group

A large chunk of machine learning (although not all of it) is concerned with predictive modeling, usually in the form of designing an algorithm that takes in some data set and returns an algorithm (or sometimes, a description of an algorithm) for making predictions based on future data. In terminology more friendly to the philosophy […]... Read more »

Big data, prediction, and scientism in the social sciences

by Artem Kaznatcheev in Evolutionary Games Group

Much of my undergrad was spent studying physics, and although I still think that a physics background is great for a theorists in any field, there are some downsides. For example, I used to make jokes like: “soft isn’t the opposite of hard sciences, easy is.” Thankfully, over the years I have started to slowly […]... Read more »

Intro to External Pulsed Plasma Propulsion (EPPP)

by Jason Carr in Wired Cosmos

External Pulsed Plasma Propulsion (EPPP)  is something that’s been discussed for some time. In fact, it was originally proposed by Stanislaw Ulam way back in 1947. Unfortunately the public perception of atomic technology as well as pieces of otherwise well meaning legislation have called into question the feasibility of spacecraft that operate using this advanced … Read More →...

The Curse of the Internet

by Aurametrix team in Health Technologies

It's hard to imagine our lives without the Internet  - either mobile or desktop. The Internet has become a catalyst of innovation, an essential tool in business and social life. It brought new levels of participation and access to knowledge. It enabled new forms of interaction, albeit mostly utilized for entertainment purposes. But despite all the advantages and conveniences, does the Internet really serve us or is it the other way around?... Read more »

Variant Annotation in Coding Regions

by Daniel Koboldt in Massgenomics

The analysis of NGS data comes with many challenges — data management, read alignment, variant calling, etc. — that the bioinformatics community has tackled with some success. Today I want to discuss another critical component of analysis that remains an unsolved problem: annotation of genetic variants. This process, in which we try to predict the […]... Read more »

Kleene’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

In 1936, Alonzo Church, Alan Turing, and Emil Post each published independent papers on the Entscheidungsproblem and introducing the lambda calculus, Turing machines, and Post-Turing machines as mathematical models of computation. A myriad of other models followed, many of them taking seemingly unrelated approaches to the computable: algebraic, combinatorial, linguistic, logical, mechanistic, etc. Of course, […]...
