Model Ensembles for Sports Forecasting

A researcher trained 11 independent models to project the 2026 World Cup, yet only a single model delivers a definitive champion, obscuring the sensitivity to internal hyper‑parameters. The ensemble approach revealed four distinct champion predictions, illustrating how choice of feature engineering, loss functions, and training splits can drive divergent outcomes in sports analytics. This highlights the need for uncertainty quantification in predictive pipelines, especially when high‑stakes decisions hinge on a single output. Build 11 Models

Local Optimisation vs. Systemic Performance

An analysis of last‑mile delivery networks shows that pursuing local efficiency—such as minimizing individual route time—can undermine overall system throughput. By modelling truck routing under varying traffic and demand scenarios, the study demonstrates that strictly locally optimal choices lead to congestion and higher aggregate delays. The findings caution against blind adoption of micro‑level metrics in logistics, urging a shift toward holistic performance indicators that capture system‑wide effects. Local Efficiency
