Biases in Expected Goals Models Confound Finishing Ability

no code implementations18 Jan 2024 Jesse Davis, Pieter Robberechts

We found that sustained overperformance of cumulative xG requires both high shot volumes and exceptional finishing, including all shot types can obscure the finishing ability of proficient strikers, and that there is a persistent bias that makes the actual and expected goals closer for excellent finishers than it really is.

Elastic Product Quantization for Time Series

1 code implementation4 Jan 2022 Pieter Robberechts, Wannes Meert, Jesse Davis

Analyzing numerous or long time series is difficult in practice due to the high storage costs and computational requirements.

Leaving Goals on the Pitch: Evaluating Decision Making in Soccer

no code implementations7 Apr 2021 Maaike Van Roy, Pieter Robberechts, Wen-Chi Yang, Luc De Raedt, Jesse Davis

Our key conclusion is that teams would score more goals if they shot more often from outside the penalty box in a small number of team-specific locations.

Predicting gait events from tibial acceleration in rearfoot running: a structured machine learning approach

no code implementations29 Oct 2019 Pieter Robberechts, Rud Derie, Pieter Van den Berghe, Joeri Gerlo, Dirk De Clercq, Veerle Segers, Jesse Davis

Thus, results indicate that a structured recurrent neural network machine learning model offers the most accurate and consistent estimation of the gait events and its derived stance time during level overground running.

A Bayesian Approach to In-Game Win Probability in Soccer

no code implementations12 Jun 2019 Pieter Robberechts, Jan Van Haaren, Jesse Davis

First, we demonstrate that in-game win probability models for other sports struggle to provide accurate estimates for soccer, especially towards the end of a game.
