How It Works
Confidence value
A number, usually between 0 and 1, that a model reports alongside its answer to say how sure it is. It is useful for deciding whether to act automatically or send a case to a person. A confidence value is not a guarantee: calibration is measured across many predictions, so a confident single answer can still be wrong.
