The most important spatial reference on a ⚽️pitch? Coordinate systems of data providers seem to suggest corner flags (@OptaPro @StatsBomb @Wyscout) or center mark (@TRACAB_). Since dimensions vary, this results in distortions and ambiguous coordinates. #soccer #analytics

In case you missed the presentation “The Origins and History of the Social Networks Perspective”, I left the workshop video on my personal webpage! (section: Short Workshops): aespinosarada.com/teaching #sna #socialnetworks #networkscience
I will be teaching a one day workshop about the origins and history of the social networks perspective. This course follows a compilation of interviews and podcast that we are doing with @FranciscaOrtizR in @NetworksPodcast! xitter.cf/aespinosarada/status/1…

Preprint arxiv.org/abs/2307.10411 submitted just in time. Algorithm extends any match outcome model to @FIFAWWC winning probabilities in split second, w/o simulation.

A: no simulation at all. Given any match outcome model, tournament winning probabilities can be computed exactly - and in the time of fewer than 500 simulation runs. (2/4)

While the preprint is being polished, here are the results for a simple model based on the @FIFAcom World Ranking.
Joint work with Gordana Marmulla and @ivanasmokovic. All hoping for a different outcome. (4/4).

The key observation is that team trajectories are dependent only after mixing. Single team trajectories can therefore be computed from joint probabilities of pairs of teams advancing together. (3/4)

Q: How many simulation runs to approximate winning probabilities for #FIFAWWC ? 10,000 ? 100,000 ?
