We've Outranked 99.92% Of FIFA World Cup Predictions On Superbru

July 16, 2018 at 9:22 AM

After a FIFA World Cup full of upsets, the South African data scientists at Principa outranked 99.92% of people on popular sports predictor site, Superbru.

Principa’s football world cup score predictions are done using various predictive analytics methods. Each method’s predictions have been submitted on Superbru.com. The best-performing algorithm uses the Bayesian Inference method. The model has been automated to adopt a machine learning approach in that it reselects variable and parameters every time it is run, adapting to how the world cup is unfolding. Results of games from previous rounds inform predictions for the next round and the model is proving more accurate than 98.81% of other Superbru predictions at the end of the tournament.

The machine learning component can take it a step further, though, by also learning from match results within the current round and updating every day. This yields slightly different predictions to the ones the model makes at the start of a round, and Principa have also been adding these predictions to Superbru. Using the latest available data is proving a successful strategy, as it outperforms the other predictions by more than 1%, beating 99.92% of Superbru participants.

The predictions are available on their website: https://wonders.principa.co.za/principa-predicts-football-world-cup-2018
