How do I choose the right validation metrics for my model?

Choosing the right validation metrics depends on your model type and the problem you're solving. Are you working on a classification or regression task?

I'm working on a classification task.

For classification tasks, common metrics include accuracy, precision, recall, and F1 score. Do you have a specific goal in mind?

I want to minimize false positives.

In that case, you might want to focus on precision and the F1 score, as they balance false positives and false negatives. Would you like to know how to calculate these metrics?

Yes, please explain how to calculate precision and F1 score.
