Confidence score to validate the output

[Aj-232425]

Hi,

This is wonderful lib. While digging in, i had come across one query. That too required badly. What if i want to apply it to millions of addresses. How would I got to know if some % of address are wrong parsed/normalized/classified. Is there any way to find confidence score/probability of output being some x% true and we can set it as threshold value. So above that threshold we don't need to validate manually.
Hoping for response.
Thanks & Regards,
Aj
