Forms AI - Can the ML Extractor developed under Forms AI be trained?

if you only have a single type of structured document, you are on the right path in choosing Forms AI. Forms AI is built to handle skewed, native/scanned scenarios, so when you’re training your Forms AI model, make sure to add a combination of native/scanned/skewed etc. documents to train your model.

Once you have trained the forms AI model do check the accuracy by testing some files. from my experience, Forms AI does a very good job in predicting values for documents, hence you should test it out to determine if forms AI is still the best solution.

OOTB means Out-of-the-box. UiPath has many OOTB models and for a general document you can use the document understanding ML model. If you want to continuously retrain your model over time, you can explore this option.
