Bias–Variance Tradeoff: MCQ Practice
The bias–variance tradeoff explains why models with too little capacity underfit and models with too much capacity overfit. These MCQs help you connect training vs validation curves, model complexity, data size and regularization to generalization error.
Finding the Sweet Spot
Good models balance bias and variance: simple enough to generalize, but flexible enough to capture the signal in the data.
Typical Generalization Workflow
Choose Model → Train → Evaluate on Validation → Adjust Complexity/Regularization → Re‑evaluate
