How do metrics influence the choice of machine learning models?

Metrics play a crucial role in model selection by providing quantitative measures of performance, helping to compare different models.

What are some common metrics used for model evaluation?

Common metrics include accuracy, precision, recall, F1 score, and AUC-ROC, each serving different purposes depending on the problem.

Can you explain how to choose the right metric for a specific problem?

Choosing the right metric depends on the problem type; for instance, use precision for imbalanced classes and accuracy for balanced datasets.

What happens if I choose the wrong metric?

Choosing the wrong metric can lead to misleading conclusions, resulting in poor model performance and ineffective decision-making.
