The Microsoft Engine That Nailed The World Cup Is Predicting Every NFL Game - Here Are Its Picks For Week 12

Microsoft's Cortana had one of its worst weeks of the NFL season, correctly predicting just eight of 14 Week 11 games.

It's now 105-56 (65%) on the season.

It was a big week for underdogs in low-profile games. the Buccaneers over Redskins and the Texans over Browns were both upsets, based on Cortana's numbers.

Cortana is a Windows phone virtual assistant that uses a Bing Predicts algorithm to predict every NFL game. It began at the World Cup, where it correctly predicted 15 of 16 knockout stage games, and now it has moved on to the NFL.

It picks games straight-up, not against the point spread. Its 105-56 record is close to the record of Vegas favorites (104-54-3) and Nate Silver's ELO model (111-50). ELO went 8-6 in Week 11, Vegas favorites went 7-6-1.

8-6 is the model's second-worst week of the year. We'll see if it can make a comeback over the next six weeks.

Here are Cortana's picks for Week 12 as of Tuesday night. We'll update them throughout the week if they change (Vegas favorites in parentheses):

• Kansas City Chiefs vs. Oakland Raiders - Chiefs win, 82% chance (Chiefs -7)
• Cleveland Browns vs. Atlanta Falcons - Falcons win, 53.3% chance (Falcons -3)
• Tennessee Titans vs. Philadelphia Eagles - Eagles win, 83.9% chance (Eagles -11)
• Detroit Lions vs. New England Patriots - Patriots win, 76.7% chance (Patriots -7)
