I’m working on https://www.dragondictionary.com, a Chinese-English dictionary aimed at Chinese learners. I am building it because there’s no good desktop alternative to Pleco at the moment.
The article doesn't explain what is actually going on to produce the second chart, but here is a guess. Assume people have a true ability x, an estimated ability y which is x + some unbiased noise, and a test score z which is also x + some unbiased noise. If you take a sample and collect the lowest quartile of test scores z, then the average of the estimated abilities y in that group is higher than z because the y are produced centered at x rather than centered at z. By collecting the lowest quartile of test scores, you didn't just get the dumbest people, you also got the people who happened to perform badly on the test that day. These people may be estimating their ability accurately, in which case the estimate would be higher than their randomly bad performance that day.
This seems like too obvious a mistake to not have been noticed for this long though.
ML is a shiny object with often no discernible ROI but occasionally very large ROI, and companies are understandably nervous about missing out. Spending a small amount to hedge their bets isn't necessarily irrational.
Neliti | Full-stack developer | Jakarta | FULL-TIME | REMOTE
We are a small team working to change the way academic research is published and make scientific work free of paywalls. We run neliti.com, Indonesia's largest repository of academic research (~3m users/mo), and are beginning to sell software to universities to manage their journals. This is a great opportunity to get in on ground floor with a successful startup, with a lot of freedom and opportunity for personal growth.
We're looking for talented full-stack developers to join our team who like well-defined tasks and a lot of freedom. Our backend is Django, frontend Vue.js, so experience in these is a bonus. Remote or Jakarta.
Everyone using UTC would be chaos. Imagine organising a remote meeting - you’d have to figure out which hours each party would be awake, by googling “waking hours in Germany” for example.
The reverse question is equally interesting - to what extent can we influence the activity of our immune system by controlling stress levels, practicing mindfulness, and the like? I think there is a lot still to be discovered about this.
