Ken Regan, whose work has been mentioned and discussed on this blog many times (and in many other places as well), will be giving a TEDx talk live in a little more than half an hour from now, at 10:40 a.m. ET. The primary focus of Regan's work has been to develop a sophisticated algorithm to help detect chess cheaters, and as an added side benefit it can be used to evaluate players' performances in various interesting ways. (One surprising result is that contrary to popular belief, the FIDE ratings have not been inflating over the years but have been rather stable.)
The live stream for the TEDx event is here, with more info here and here.
