What is Precision in the context of evaluating a model's performance?
What is Precision in the context of evaluating a model's performance?
- It evaluates the overall correctness of the model's predictions.
- It is the fraction of positive cases that are correctly identified.
- It considers the cases where the model predicts True Positives and False Negatives. (correct)
- It is the fraction of negative cases that are correctly identified.
Why is Precision considered an important evaluation criteria for a model?
Why is Precision considered an important evaluation criteria for a model?
- High Precision suggests a model is perfect.
- Low Precision means the model is accurate but not reliable.
- Low Precision leads to complacency and more false alarms. (correct)
- Precision has no impact on model performance.
What does Recall measure when assessing a model's performance?
What does Recall measure when assessing a model's performance?

- The cases where the model predicts False Positives.
- The fraction of negative cases that are correctly identified.
- The total number of predictions made by the model.
