I have tested the ML extractor activity and below are some of the major issues that I faced:

  1. Unable to extract “item” information i.e. information present in tabular form from the invoice.
  2. If we process multiple invoice with same template, sometimes it does not extract complete information from all the invoices. For e.g out of 10 invoice of the same template, its extracting “due-date” from 9 invoices and not extracting the same field for one of the invoices.

Please suggest for the same if there is any solution/fix for this.

Hi Team,

ML extractor is not working for some of the invoices. It failed to extract invoice no, Invoice date, Due date, Items data from this invoice. It is extracting Name, address related fields only. How much confidence score should I use for accurate results? now I am using 40%. Please provide me a solution.

@atul.trikha you have to use the api key provided with your cloud community version specifically for the Templateless Invoice Extraction.
https://demo.uipath.com/[Your User ID]/portal_/licensing

You should have an api key for Computer Vision, Templateless Invoice Extraction and Templateless Receipt Extraction

Hi,

I have tested the given sample program with attached sample Invoice. 01.pdf (145.2 KB)
It has Romainan and GBP totals. By default, its selecting Romanian currency and when I tried to choose GBP value, but the json output still picking the Romanian value.

Same issue for Vendor Address aswell. Updated values are not getting reflected in json. Could you please validate.

Thanks,
Harish Vemula

Hello @Stabbathehut,

Can you please check that the machine learning extractor is correctly configured? If you can’t get this working, can you please attach a workflow and a sample file to test against?

Thanks,

Ioana

Hi Harishvk,

I am assuming that you are using the sample project. If that is the case, you need to make some small changes to capture the ValidatedOutput from the Present Validation Station Activity.

The sample project only outputs the ML Extracted Output - you need to add a variable in the Output of the Present Validation Station activity and then use a Write File activity and serialize that variable. That will contain the human validated results.

Data Extraction Scope: The results of extractor ‘MachineLearningExtractor’ contain duplicates ‘date’. The extractor should return a single ResultsDataPoint entry for each requested field.
