Researchers created a database of over 87,000 games spanning the course of 26 years in European soccer leagues between 1993 and 2019. For simplicity, they chose to eliminate tied games.
Factoring in things like strength of schedule, for each new match they used a logistic regression algorithm a classification algorithm that helps assign data into discrete buckets, like labeling emails as either spam or not spam-to predict the probability of their match's outcome. Researchers found a clear difference between the predictability of games played 10 years ago and matches played today. In a German league, for example, the model has an accuracy of 60 to 65 percent in the early 2000s, and 80 percent accuracy with data from the late 2010s.

The Tools of Copernicus
WAY BACK IN 1508, WITH ONLY LIMited tools at his disposal, Nicolaus Copernicus developed a celestial model of a heliocentric planetary system, which he described in hist landmark work De revolutionibus orbium coelestium. It was a complete overhaul of our conception of the universe-one that, unfortunately, earned him the ire of the Catholic church for decades after his death-and forever changed the way we look at the stars.
Building a Sixth-Generation Bomber Raptor
THE GLOBAL COMBAT AIR Programme (GCAP)-a project by the U.K., Italy, and Japan to develop a sixth-generation stealth fighter-has been busy at the drawing board reshaping its vision of the future of air warfare. And judging by the new concept model unveiled at this year's Farnborough air show, that future has big triangular wings.
