How do I choose a loss function for my model?

Choosing a loss function depends on your specific problem. Are you working on a regression or classification task?

I'm working on a classification task.

For classification, common loss functions include binary cross-entropy for binary classification and categorical cross-entropy for multi-class problems.

What if my classes are imbalanced?

In cases of class imbalance, you might consider using weighted loss functions or focal loss to give more importance to the minority class.

Can you give me an example of a weighted loss function?

Sure! In binary classification, you can use a weighted binary cross-entropy where you assign a higher weight to the minority class.
