Microsoft’s Cortana had its best week of the NFL season in Week 5, correctly predicting 13 out of 15 games.
It’s now 47-29 on the year.
The Windows phone virtual assistant, which is powered by a Bing Predicts algorithm, is predicting every NFL game this year after correctly picking 15 out of 16 World Cup knockout stage games.
The algorithm got off to a mediocre start and had a dismal 5-8 record in Week 4, but it caught fire in Week 5. The only games it missed were Patriots-Bengals and Bills-Lions.
Week 5 was a big week for favourites across the board. Vegas favourites went 12-3 straight-up, and Nate Silver’s ELO model went 13-2.
Was Week 5 just an aberration? Or is Cortana about to go on a hot streak like we saw during the final two weeks of the World Cup?
