Episode notes
Generative Bayesian Modeling in Sports
- Bayesian models use generative frameworks to specify how data is generated and then work backwards with observed data.
- This approach pools information across players, matches, and contexts to manage sports data's complexity and uncertainty.
Balance Model Complexity and Efficiency
- Balance model complexity and computational efficiency to handle large, complex sports data.
- Strive for simpler models that capture most value but are computationally feasible.
Cut Models Hack Bayesian Performance
- Cutting dependencies in Bayesian models can prevent unwanted information flow between variables.
- This 'cut model' approach can improve performance despite being theoretically unprincipled.
