A few brief items…
- I’ve made a little web page for sharing results of analyses I do (mostly these will be posterior samples and marginal likelihood values). I’ll aim to put things up when they’re sufficiently mature and ‘finished’, in the hope that someone might use them for actual science.
- Check out this fascinating post about an experiment on reddit, where anyone with could contribute to an image by painting one pixel at a time, but had to wait a few minutes between pixel edits. It’s amazing what emerged (via Diana Fleischman on Twitter).
- A professor at Carnegie Mellon has put a twist on multiple choice exams, by asking students to assign a probability distribution over the possible answers, and then grading them using the logarithmic score. This is sufficiently awesome that I might try it out one day. One way of improving this (and scaring students even more) would be to allow the students to assert a probability distribution that doesn’t factor into an independent distribution for each question (via Daniela Huppenkothen).
