An online contest for data scientists has produced a great leap forward in efforts to predict when someone with epilepsy is going to have a seizure. The winning team used data on electrical activity in the brain to develop an algorithm that predicted seizures 82 percent of the time.
That “blew the top off” previous efforts, says Brian Litt, a professor of neurology and bioengineering at the University of Pennsylvania who helped oversee the competition. In the past, he says, researchers have struggled to find an algorithm that did better than chance.
