SPORTS ANALYTICS
A novel explainable artificial intelligence framework using knockoffs techniques with applications to sports analytics
The rapid integration of black-box Machine Learning (ML) models into critical decision-making scenarios has triggered an urgent call for transparency from stakeholders in Artificial Intelligence (AI). This call stems from growing concerns about the deployment of models whose decisions lack justification, legitimacy, and detailed explanations of their behavior. To address these concerns, Explainable Artificial Intelligence (XAI) has emerged as a crucial field, focusing on methods and processes that enable the comprehension of how AI systems make decisions, generate predictions, and execute their functions.

Rigorous FDR Control
Ensuring statistical reliability in feature selection for trustworthy AI explanations.
Our XAI framework utilizes advanced statistical knockoff techniques to identify the most informative predictors while maintaining a controlled False Discovery Rate (FDR). This ensures that explanations are statistically reliable and mitigates the risk of incorrect conclusions. By rigorously controlling the FDR, our method provides robust and interpretable insights, enhancing informed decision-making across various business domains beyond sports analytics.
Case Study: NFL Playoff Prediction
We successfully applied our novel XAI framework to predict NFL playoff outcomes, demonstrating its efficacy in a highly competitive sports analytics domain. The framework identified four crucial seasonal statistics from a total of 17 that are most predictive of playoff success: Rushing Attempts (R Att), Rushing Yards (R Yds), Rushing Touchdowns (R TD), and Receiving Touchdowns (C TD).
This streamlined feature set not only improved predictive accuracy but also provided clear, interpretable insights for strategic decision-making in professional football. For instance, teams with strong rushing metrics often perform better due to game tempo control and reduced opposing team scoring opportunities, highlighting the practical value of these identified features.
| Model & Features | Accuracy | F1-score |
|---|---|---|
| Logistic Regression (Full Model, 17 features) | 0.82 | 0.82 |
| Logistic Regression (Simplified Model, 4 features) | 0.87 | 0.87 |
| XGBoost (Full Model, 17 features) | 0.79 | 0.80 |
| XGBoost (Simplified Model, 4 features) | 0.85 | 0.85 |
| Decision Trees (Full Model, 17 features) | 0.59 | 0.60 |
| Decision Trees (Simplified Model, 4 features) | 0.77 | 0.77 |
Our framework's ability to select a concise set of features leads to superior predictive performance. Using only the four key features identified by knockoffs, the logistic regression model achieved the highest accuracy of 87%, outperforming a full model with all 17 features by 5%. This demonstrates that simpler, explainable models can often be more effective than complex black-box models when built on robust feature selection.
