These are my links for March 14th through March 15th: Google Refine – a power tool for working with messy data (formerly Freebase Gridworks) Interpreting Prediction Market Prices as Probabilities – While most empirical analysis of prediction markets treats prices of binaryoptions as predictions of the probability of future events, it has recently been argued thatthere is little existing theory supporting this practice. We provide relevant analyticfoundations, describing sufficient conditions under which prediction markets pricescorrespond with mean beliefs. Beyond these specific sufficient conditions, we show thatfor a broader class of models prediction market prices are usually close to the meanbeliefs […]

Watson, an IBM supercomputer, has done pretty well against Jennings and Rutter in a practice match.
This video provides a pretty intuitive visualization and audibilization of different sorting algorithms (insert sort, bubble sort, selection sort, merge sort, gnome sort). Even without explaining the algorithms with pseudo-code, or the like, I daresay one can get a decent sense of how they work from this:
These are my links for May 27th through July 28th: Statistical Modeling: The Two Cultures – There are two cultures in the use of statistical modeling to reach conclusions from data. One assumes that the data are generated by a given stochastic data model. The other uses algorithmic models and treats the data mechanism as unknown. The statistical community has been committed to the almost exclusive use of data models. This commitment<br /> has led to irrelevant theory, questionable conclusions, and has kept statisticians from working on a large range of interesting current problems. Algorithmic modeling, both in theory and […]
Beautiful MRI imagery of food, from Inside Insides: v
from “The Cyberiad” by Stanislaw Lem: Come, let us hasten to a higher plane, Where dyads tread the fairy fields of Venn, Their indices bedecked from one to n, Commingled in an endless Markov chain! Come, every frustum longs to be a cone, And every vector dreams of matrices. Hark to the gentle gradient of the breeze: It whispers of a more ergodic zone. In Riemann, Hilbert or in Banach space Let superscripts and subscripts go their ways. Our asymptotes no longer out of phase, We shall encounter, counting, face to face. I’ll grant thee random access to my heart, […]
