Question

In spam email detection, which of the following will be considered as "False Negative"?

• A. When a legitimate email is accurately identified as not spam.
• B. When a spam email is mistakenly identified as legitimate.
• C. When an email is accurately recognized as spam.
• D. When an email is inaccurately labeled as important.

Hint:

False Negatives in spam detection result in spam emails being incorrectly classified as legitimate.

Answer 1

The Correct Option is B

A False Negative occurs when a spam email is mistakenly classified as legitimate, meaning the model fails to identify it as spam. This is problematic because spam emails are allowed through the system and could lead to unwanted consequences, such as security breaches or spam content being delivered to the user’s inbox. In contrast, False Positives occur when legitimate emails are incorrectly flagged as spam.
