How do I evaluate the performance of NLP models?

To evaluate NLP models, you can use metrics like accuracy, precision, recall, and F1 score. What specific model are you working with?

I'm working with a sentiment analysis model. Are there specific metrics I should focus on?

For sentiment analysis, precision, recall, and F1 score are crucial, especially if your classes are imbalanced. Do you have a validation dataset?

Yes, I have a validation dataset. How can I calculate these metrics?

You can use libraries like scikit-learn in Python. They provide functions to calculate these metrics easily. Would you like a code example?

Yes, that would be great!
