What are some common methods for evaluating AI models?
Common methods include accuracy, precision, recall, F1 score, ROC-AUC, and confusion matrix.
Can you explain what precision and recall mean?
Precision measures the accuracy of positive predictions, while recall measures the ability to find all relevant instances.
How do I choose the right evaluation method for my model?
It depends on your specific use case. For example, if false positives are costly, prioritize precision.
What is the F1 score and when should I use it?
The F1 score is the harmonic mean of precision and recall, useful when you need a balance between the two.
