6. Olga Petrova, @tyoushe Predict Results at FIFA World Cups? ⚽
7. Olga Petrova, @tyoushe FIFA Would Cup Dataset Training: 1930 - 2014 Validation: 2018
8. Olga Petrova, @tyoushe Features • Previous wins count for Team A minus previous wins count for Team B • in total • in last 12 years • Previous wins count for Team A against Team B • in total • in last 12 years • at the same stage • The game is played in Team A or Team B's home country • Stage
9. Olga Petrova, @tyoushe Target • Group stage: • Team A won • Team B won • Draw • Play-off game: • Team A won • Team B won

11. Olga Petrova, @tyoushe Most Valuable Features • Previous wins count for Team A minus previous wins count for Team B • in last 12 years • Previous wins count for Team A against Team B • in total • The game is played in Team A or Team B's home country • Stage
12. Olga Petrova, @tyoushe Insights • Teams that won more games in last 12 years perform better • Teams playing in the home country perform better • Weaker teams perform better on a higher stage • Teams that lost more games against this opponent in the past perform better
