Abstract

Rad proučava VAEP model koji vrednuje doprinos svakog igrača dodjeljivanjem ocjene za svaku akciju koju napravi na lopti. Ako je akcija više pridonijela napadu u postizanju pogotka bit će pozitivno ocijenjen u suprotnom negativno. Prolazi se kroz podatke koji su dostupni, iz dostupnih informacija za akcije se generiraju nove koje se koriste za strojno učenje. Model se optimira kako bi imao što bolja predviđanja. Po uzoru na naučeni model radi se novi modeli koji su svi trenirani različitim utakmicama. Ocjenjuju se igrači jedne lige te se proučava kakav stil igre pristaje kojim igračima.

Abstract (english)

This paper examines VAEP model which evaluates contribution of a football player by grading every action he makes in a game. If his action contributed to developing their attack and got his team closer to the oppositions goal he will get a positive grade, but if the action benefited the opposition grade will be negative. We go through available data and generate new features for football actions from already existing information. Model is trained by a machine learning algorithm and optimised so that model gives best possible predictions. On a same basis we develop six different models where each contains matches from exclusively one league. We evaluate players from one league with every model and then analyse the differences in evaluation and preferences of players different leagues style of play.
