The Specifics
Below is information on what data will be provided and how the prize money will be divided and allocated.
Click here for the Terms and Conditions.
Player data dating back to the 2010 AFL season will be provided upon entering. This includes:
- Contested and uncontested possessions
- Effective disposals and disposal efficiency
- Brownlow Votes
- AFL Fantasy and Supercoach Scores
- Time on Ground
The metric used to determine the winner will be the ‘Mean Squared Error‘ over all predictions, based on the actual Brownlow votes received compared to predicted Brownlow Votes received.
For example, the Betfair Data Scientists’ Brownlow Model predicted Tom Mitchell to poll 35.48 votes last season, while he only actually polled 28. Thus, the Squared Error for this individual prediction would was (35.48-28)^2=56.04. On the other hand, if our model had correctly predicted votes, the Squared Error would have been 0. The winner of the Datathon will be the participant with the lowest Mean Squared Error over all predictions.
It is important that answers are submitted in the format that is provided in ‘Betfair Brownlow Datathon Submission.csv’.
We will assume 0 predicted votes for any missing values. For example, if someone doesn’t provide a prediction for ‘P Dangerfield’ we will assume they predict 0, and mean squared error will be calculated accordingly.
Winners will be announced via email and on this Betfair Hub page after the Competition concludes on or around 24 September 2019.
Prizes will be awarded to the top 10 entries in the form of a loaded Mastercard/Visa gift card.
Betfair entries that are in the Datathon are not eligible for prizes.

Final Submissions are due by 17:59 AEST on 23 September 2019.
The name of your prediction model will be published on the Betfair website and will be visible to members of the public. Please bear this in mind when naming your model. Offensive names will not be published.
Submissions must be in a CSV format, any submissions that are not in the correct format will not be accepted;
To submit your output, email your final submission to datathon@betfair.com.au.
FAQ's
- Some of the players are missing. i.e. there is only one listing of A Brayshaw, when there should be two Brayshaws.
Player names are in the format {firstname initial}{surname} as some small merging of datasets was required to create the dataset for this competition. This means some players with identical names are not uniquely identifed. Don’t worry about providing a submission for these players; you can provide a prediction or no prediction at all and you will not be penalised as we will have to exclude these players from scoring. However, do not make changes to the submission file to try and distinguish between these players.
