For IDR, is Adaptive Learning done for recognizing Supplier Name?

Summary:

1) Is there no adaptive learning done for recognition of Supplier Name? In the IDR user guide doc published by Oracle, I noticed it's not in the list that of "Attributes that are supported for header level learning."

2) In the scenario described below, who is the adaptive learning being done for? The supplier that IDR initially recognized, the correct supplier that we updated it to, or neither?

• We have several suppliers whose invoices come in consistently assigned to incorrect vendors. For most, there doesn't appear to be any clear reason for it. Our AP team has been attempting to correct scanned invoices via the interactive viewer (i.e. clicking into the text box for Supplier on the invoice header and highlighting the supplier name on the invoice image).
