What is AI model evaluation and why is it important?

AI model evaluation is the process of assessing how well a model performs on a given task. It's crucial for ensuring accuracy and reliability.

What metrics are commonly used for evaluating AI models?

Common metrics include accuracy, precision, recall, F1 score, and AUC-ROC, depending on the type of task.

How do I choose the right evaluation metric for my model?

Choosing the right metric depends on your specific goals. For example, if false positives are costly, precision might be more important.

Can you explain overfitting and how it affects evaluation?

Overfitting occurs when a model learns noise in the training data, leading to poor performance on unseen data. It can skew evaluation results.

What are some best practices for model evaluation?

Best practices include using a separate validation set, cross-validation, and ensuring your evaluation metrics align with your business objectives.
