Note
You cannot train the “Credits” or “Currency” properties in the Amount Group
locator.
For problem invoices, you can define templates. Templates are not needed for the
extraction process, but can help improve extraction quality for difficult or unusual
invoice layouts. For all fields on the document that work correctly, you can use the
definitions from the training set. For fields that have failed, you can change the field
settings or define additional fields in the template.
Setting Up Classification
Ascent Xtrata Pro Project Builder has three different classifiers:
• Layout Classifier
• Adaptive Feature Classifier
• Instruction Classifier
The following sections include general instructions for setting up the different
classification engines for a selected class. For details about the different classifiers,
see Classification.
Layout Classifier
The Layout Classifier is an image classifier. It performs image-based classification by
analyzing the graphical elements of an image. To enable this classifier for a class, it is
normally sufficient to add one or two representative documents and to train the
project with these examples.
