To calculate the sensitivity of a detector, you need to assess its ability to correctly identify positive samples. The formula is: Sensitivity = (True Positives) / (True Positives + False Negatives). This ratio measures the proportion of actual positives accurately identified by the detector.
FAQs & Answers
- What is sensitivity in detector performance? Sensitivity measures the ability of a detector to correctly identify actual positive cases, calculated as true positives divided by the sum of true positives and false negatives.
- Why is sensitivity important when evaluating detectors? Sensitivity is crucial because it indicates how effectively a detector can find positive samples without missing them, which is vital for applications like medical testing or quality control.
- How does sensitivity differ from specificity? While sensitivity measures correct identification of positives, specificity measures the detector's ability to correctly identify negatives, helping balance overall accuracy.
