How do we evaluate the performance of AI models?

Evaluating AI models typically involves metrics like accuracy, precision, recall, and F1 score. What specific model are you interested in?

I'm looking at a classification model. How do I choose the right metric?

For classification models, it depends on your goals. If you want to minimize false positives, focus on precision. If false negatives are more critical, recall might be your priority.

What about overfitting? How can I tell if my model is overfitting?

You can check for overfitting by comparing the performance on training and validation datasets. If the training accuracy is high but validation accuracy is low, your model may be overfitting.

Are there techniques to prevent overfitting?

Yes, techniques like cross-validation, regularization, and pruning can help prevent overfitting. Would you like to know more about any of these?
