### Use of LBPHFaceRecognizer (python)

I am testing the python version of LBPHFaceRecognizer and results seems not bad, but I noted something strange.
Making the prediction, let's say:

```
label= face_recognizer.predict(gray)
print('prediction', label)
```

I see that `label`

is a tuple with 2 values, the first is the prediction, the second I guess is the probability. Now when probability is low the prediction is fine, while when it is high, I have false positive.

Maybe this value is not the probability, so the question is, what is its real meaning ?
Thanks
