Need help with understanding of confidence scores|HF Transformers Question Answering
Hello All,I am working on the Question-Answering problems and would like to know how the model confidence scores are calculated ? What is the formula as well as theory behind it ?I get scores as 4.5, 3.5678, 9.456 etc. for the predicted answers and sometimes these scores are negative values.I am not sure if the confidence score can be -ve if it’s the product of two softmax probabilities.Thanks,
