I've been using form recognizer custom model to train a detector able to recognize signatures on ID documents, but after the training, the accuracy of signature field is always very low or even zero, regardless the fact that all the documents are signed and I'm using between 20 and 50 samples of high quality . Could you provide an advice for this issue.
