This preprint introduces a Transformer-based TabTransformer model that generates dense embeddings for heterogeneous football event data, addressing the limitations of traditional one-hot or ordinal encodings. By capturing latent semantic dependencies among categorical features like action types and body parts, the approach improves probability calibration for downstream tasks such as play style recognition and match outcome forecasting. The method demonstrates superior performance on prediction tasks, offering a robust framework for applying self-attention mechanisms to structured tabular sports analytics.
A Universal Dense Football Event Representation Based on TabTransformer
arXiv:2606.09327v1 Announce Type: new Abstract: Football event data constitute a rich spatiotemporal source for quantitative analysis of player actions in team sports. These datasets contain heterogeneous features, combining continuous location coordinates with categorical variables such as action type, action outcome, and body part. Such data have been applied in sports analytics for match outcome forecasting, player evaluation, and tactical pattern recognition. However, existing approaches predominantly encode categorical features using one-hot or ordinal embedding representations, overlooking the intrinsic semantics of action descriptors. The Transformer is a deep neural network architecture based on self-attention that captures dependencies between input features at arbitrary positions. We propose and implement a Transformer-based model to learn latent dependencies among categorical event features and produce dense representations of football events. By encoding categorical features as learned embedding vectors, sport-specific action semantics are captured during pretraining, enabling the representations to support downstream tasks such as action value estimation and play style recognition. Empirical evaluation shows that the embedding representations yield superior probability calibration over task-specific baselines on the downstream prediction tasks, as measured by Brier score.
