## PLoS topic page on ABC

June 6, 2012
By

A few more comments on the specific entry on ABC written by Mikael Sunnåker et al…. The entry starts with the representation of the posterior probability of an hypothesis, rather than with the posterior density of a model parameter, which seems to lead the novice reader astray. After all, (a) ABC was not introduced for

## PLoS computational biology meets wikipedia

May 26, 2012
By

Robin Ryder pointed out to me this new experiment run by PLoS since March 2012, namely the introduction of a new article type, “called “Topic Pages” and written in the style of a Wikipedia article“. Not only this terrific idea gives more credence to Wikipedia biology pages, at least in their early stage, but also

## R at Wikimania

The last Le Monde puzzle made me wonder about the ternary version of the sorting algorithms, which all seem to be binary (compare x and y, then…). The problem is, given (only) a blackbox procedure that returns the relative order of three arbitrary numbers, how many steps are necessary to sort a series of n

## R at Wikimedia

July 9, 2011

Last year Wikipedia rolled out a pilot program to use Wikipedia article creation as an assignment in the classroom. Students wrote articles on a topic area and rather than turning them into a professor and forgetting about it they upload it to Wikipedia and expose it to readers around the world. 24 schools inside the…

## Wikipedia for Kaggle Participants

July 1, 2011
By

Kaggle has released a new data-mining challenge: use data from 10 years of Wikipedia edits in order to predict future edit rates. The dataset has been anonymized in order to obscure editor identity and article identity, simultaneously adding focus to the challenge and robbing the dataset of considerable richness. I have some experience with wikipedia…
