Retraining a Field or Table ID model is not necessary if one, or some combination, of the following properties were changed in an existing field’s settings:

• Field name
• Output name
• Supervision
• Required
• Identification Supervision

Field ID models

Field ID models do not need to be retrained if any of the following layout changes are made:

• Removing fields
• Changing data types

Note that if you use existing training data to retrain a model with new fields or fields whose Multiline setting is updated, those fields won't be included in the training. They will be unsupported until you retrain the model with enough documents that include annotations of the new or updated fields. Learn more in our Incremental Training article.

Table ID models

Table ID models do not need to be retrained if any of the following layout changes are made:

• Removing fields
• Changing data types

On the other hand, Table ID models will need to be retrained after the following layout changes:

• Adding new columns
• Toggling the Multiline setting
