ASF Challenge

Main steps of the ASF challenge

01/11/2019: opening of the application (free participation)

Applications are closed

Already done! The procedures to download the datasets is very easy. Just go to the "Data" page; mock synthetic data having the same structure as the challenge data are available to the Players (up to the 17th of April); associated documentation is provided; this step allows The Players to get familiar with the information that will be used during The ASF Challenge.


The official launch of The ASF Challenge will be planned soon! It has been postponed due to the current "COVID" sanitary context. During this first exciting meeting, the teams will present themselves, the rules will be given, and the first dataset be revealed. It would be nice if at least one (maximum two) players per team could be present at this official launch. If you cannot be there, do not worry, it will be possible to attend remotely.

And then:

- The Coordinators will make available to The Players regular updates of the datasets and The Players will provide summary statistics of the predicted epidemic for the following four weeks as well as the effectiveness of the different alternative intervention strategies (the frequency this step still needs to be defined, but it will be probably once a month)

- After 3 periods of 4 weeks: the challenge is over as the epidemic has (hopefully) died out!

- Next 4-6 months: The Coordinators will analyse the different modelling solutions proposed by the different modelling teams over the course of the epidemic.

- Hopefully in March 2021: Closing ceremony of The ASF Challenge at SVEPM2021 in Toulouse, France, where all challenge outcomes will be presented to all participants (and more!)
