Governments and security companies are coming to rely more heavily on facial recognition software to locate persons of interest.
Consider a hypothetical situation. Suppose that facial recognition software can accurately identify a person
Make a model for this situation.
Use the model at right as a starting point.
Complete it by including the probabilities.
1/200,000, P(ID is correct)
P(not the suspect)
?, P(ID is not correct) ?
If a person has been identified as the suspect, what is the probability that he or she is not actually the suspect?
The desired outcome is a person who is not the suspect being incorrectly identified, or situation D.
The possible outcomes are situation D and the suspect being correctly identified, or situation A.
