Document Understanding Activities
Release notes
Release date: April 16, 2025
We are excited to announce the release of the AI Units per tenant feature. You can now allocate and track AI Units consumption at tenant level as well. In order to benefit from this change, make sure that you redeploy any running skills for the changes occur. If there are any running pipelines, they will still consume AI Units at account level until the changes occur.
Release date: April 16, 2025
- You now have a Field Name and a Field ID for both column and regular fields created in a Document Understanding project. The Field Name represents the display name of the field, meaning that you can use uppercase characters, whitespace, and any type of characters. The Field ID is automatically generated based on the Field Name. The Field Name is meant to ease your work, while the Field ID is used for training with pre-trained models.
- A new option is now available under the Dataset Diagnostic menu, the Calculator Tab. Use the Calculator Tab to modify the information about the created document type. You can update any of the following fields: Out-of-the-box document type, Number of languages, or Number of layouts. Changes done on the Calculator Tab have an impact on the size and accuracy of the entire Dataset, meaning that more labelled training data may be required.
Release date: April 16, 2025
A classification field must have at least two options to be created or edited. The same limitation applies to import or export, as follows. When trying to import a schema or a dataset which has a classification field with less than two options, you receive a warning message. When trying to export to AI Center a dataset whose schema contains a classification field with less than two options, you receive an error message.
Release Date: 4 October 2021
The UiPath.DocumentUnderstanding.OCR.LocalServer is now generally available. The package allows using UiPath Document OCR locally on the Robot machine without calling out to a OCR server and without connecting to a licensing server. This allows processing documents in parallel with multiple Robots to get higher throughput.
