In UiPath AI Center, ML Skills can be managed in various ways, allowing users to customize and control how these skills are deployed and used. The management options include:
Creating a new ML skill.
Stopping a deployed skill.
Redeploying an ML skill.
Updating to a new package version.
Rolling back to a previous version if needed.
Modifying GPU usage.
Modifying the use of AI units.
Making the skill public or private.
Deleting an ML skill when no longer needed.
This provides flexibility for both managing the ML infrastructure and optimizing resources in real-time.

According to the UiPath documentation, a UiPath Communications Mining taxonomy is a collection of all the labels applied to the verbatims in a dataset, structured in a hierarchical manner. Labels are the concepts and intents that you want to capture in the dataset to suit your specific objectives. When you import your taxonomy from a spreadsheet, you need to provide the label descriptions, which are the names of the labels and their level in the hierarchy. Label predictions and entity predictions are the outputs of the model training process, and they are not part of the taxonomy. Entity descriptions are the definitions of the entities that you want to extract from the verbatims, and they are not part of the taxonomy either.

In UiPath's AI Center, a Pipeline can be scheduled for execution either at a specific future date or with a recurring schedule. This allows for flexibility in automating the retraining or execution of machine learning models based on predefined time intervals or specific dates. For example, you can schedule a pipeline to run once on a given date or set it to run daily, weekly, or monthly, depending on the project's needs.

UiPath offers several pre-trained out-of-the-box models, and Invoices is one of the most commonly supported document types. This model is optimized to extract relevant fields such as invoicenumbers, dates, amounts, and more from structured invoices. Other common out-of-the-box models include receipts and purchase orders.
