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?

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?

The fraction of positive cases that are correctly identified. (correct)

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.

How does Recall parameter contribute to evaluating a model's performance?

It focuses on minimizing False Negatives to ensure no positive case is missed. Signup and view all the answers
