A Shiny interactive web application to quantify how robust inferences are to potential sources of bias (sensitivity analysis)

We are happy to announce the release of an interactive web application, Konfound-It, to make it easy to quantify the conditions necessary to change an inference. For example, Konfound-It generates statements such as “XX% of the estimate would have to be due to bias to invalidate the inference” or “an omitted variable would have to …

More on “Core Points”

A few additions to yesterday’s post occurred to me belatedly. First, it may be a good idea to check whether your alleged core point \(y^0\) is actually in the relative interior of the integer hull \(\mathrm{conv}(Y)\). A sufficient condition is that, when you substitute \(y^0\) into the constraints, all inequality constraints including variable bounds have …

Finding a “Core Point”

In a famous (or at least relatively famous) paper [1], Magnanti and Wong suggest a method to accelerate the progress of Benders decomposition for certain mixed-integer programs by sharpening “optimality” cuts. Their approach requires the determination of what they call a core point. I’ll try to follow their notation as much as possible. Let \(Y\) …

Institute for Advanced Study: Genomic Prediction of Complex Traits (seminar)

Genomic Prediction of Complex Traits After a brief review (suitable for physicists) of computational genomics and complex traits, I describe recent progress in this area. Using methods from Compressed Sensing (L1-penalized regression; Donoho-Tanner phase transition with noise) and the UK BioBank dataset of 500k SNP genotypes, we construct genomic predictors for several complex traits. Our …

Gork revisited, 2018

It’s been almost 10 years since I made the post Are you Gork? Over the last decade, both scientists and non-scientists have become more confident that we will someday create: A. AGI (= sentient AI, named “Gork” :-)  See Rise of the Machines: Survey of AI Researchers. B. Quantum Computers. See Quantum Computing at a Tipping …
