🎛️ Model Selection Hyperparameters
Learn about model selection hyperparameters in machine learning. Understanding cross-validation, ensemble methods, and model comparison parameters.
A 3D k-fold cross-validation arena: each fold sits around a ring with its own held-out test scatter and a live score bar, while a central fitted surface shows how complexity and regularization reshape the model.
🔬 What It Demonstrates
Raising model complexity lets the central fit hug the noisy training points more tightly, but validation-fold scores on the ring start diverging — the classic bias-variance tradeoff behind model selection.
🎮 How to Use
Adjust K folds, model complexity, and regularization to watch the fit and fold scores respond live. Switch ensemble mode to see how bagging smooths variance and boosting chases hard folds.
💡 Did You Know?
The "one-standard-error rule" says to pick the simplest model within one CV standard deviation of the top score — trading a sliver of accuracy for a model far less likely to overfit unseen data.
