The original title is 11 words: "I Pitted XGBoost Against Logistic Regression on 358 Matches. The Boring Model Won."

Short summary

Logistic regression outperformed XGBoost in cross-validation on 358 matches, demonstrating the bias-variance tradeoff in practice. This illustrates that simpler models can beat complex ones when data is limited or signal is weak. Key lesson: always baseline against simple models before adopting advanced ML techniques.

• •Logistic regression achieved better cross-validated fit than XGBoost on 358 match predictions
• •Demonstrates bias-variance tradeoff: simpler models can outperform complex ones
• •Key takeaway: always establish simple model baselines before adopting advanced techniques
