 A project in UiPath AI Center is an isolated group of resources (datasets, pipelines, packages, skills, and logs) that you use to build a specific ML solution. You can create, edit, or delete projects from the Projects page or the project’s Dashboard page. However, you can only delete a project if it does not have any package currently deployed in a skill. A package is a versioned and deployable unit of an ML model or an OS script that can be used to create an ML skill. A skill is a consumer-ready, live deployment of a package that can be used in RPA workflows in Studio. If a project has a package deployed in a skill, you need to undeploy the skill first before deleting the project. This is to ensure that you do not accidentally delete a project that is being used by a skill12.

The correct syntax for filtering both .doc and .docx Word documents is to use the wildcard *.doc*. This matches:

.doc

.docx

Any Word file variant starting with .doc

UiPath Studio uses .NET wildcardsfor file filters in activities like "For Each File in Folder".

The typical machine learning model deployment process in UiPath AI Center usually takes between 10-15 minutes1. This process involves wrapping the model in UiPath’s serving framework and deploying it within a namespace on AI Fabric’s Kubernetes cluster that is only accessible by your tenant1. Please note that the actual time may vary depending on the complexity of the model and other factors.

Partially labeled messages in UiPath Communications Mining can negatively impact model performance because incomplete or inconsistent labeling creates ambiguity for the model during training. This leads to the model receiving conflicting signals, which hampers its ability to generalize well across the dataset, resulting in reduced precision and recall in predictions. Properand complete labeling is critical to ensure the model learns accurately from the data

To iterate through all Microsoft Word documents in a local folder using the For Each File in Folder activity, you should use the filter option "*.doc*". This filter utilizes the asterisk (*) wildcard to match any number of characters, effectively capturing both .doc and .docx file extensions.

UiPath Documentation

In the Filter by field of the activity, entering "*.doc*" ensures that the iteration includes all files with names ending in .doc or .docx, which are standard extensions for Microsoft Word documents.

Other options are incorrect because:

B. Microsoft Word: This is not a valid filter pattern.

*C. " doc"**: This pattern looks for files with names ending in " doc" and does not account for file extensions.

*D. " doc, *docx"**: This is not a valid filter pattern; multiple patterns should be separated by semicolons (e.g., "*.doc;*.docx").

Therefore, the correct filter to use is "*.doc*".

Optical Character Recognition (OCR)is a method used to convert different types of documents (PDFs, scanned paper documents, images) intoeditable and searchable databy recognizing characters and their positions.

OCR is vital in Document Understanding todigitize unstructured data from images and scanned docs.

In UiPath Communications Mining, Dashboards are fully customizable pages that allow users to display relevant charts, visualizations, and insights for a specific dataset. These dashboards provide critical insights into the performance of models, labels, and other metrics relevant to the communication mining process. Users can create and adjust these dashboards to reflect specific data points, making them a powerful tool for tracking and improving model performance over time.

The error"Object reference not set to an instance of an object"occurs when the DataTable variable (dt_Reports) hasn't been initialized.

To fix this, use:

vb

CopyEdit

Assign dt_Reports = New System.Data.DataTable

Then, add necessary columns before adding rows.

Note:You cannot assign a new row (DataRow) without first initializing the DataTable.

Main-ActionCenter is a workflow that allows you to create and manage Document Understanding actions in Action Center, which is a web application that enables human intervention in automation processes. You can use Main-ActionCenter when you want to test your Document Understanding process locally, or when you want to implement an attended process that requires human validation or classification of documents. Main-ActionCenter is not recommended for unattended processes, as they do not involve human interaction.

The Machine Learning Extractor utilizes machine learning models to effectively extract data from documents, especially when dealing with varying structures or formats within the same document type. This capability is crucial in scenarios where documents do not follow a strict template and have variations in their layout or content organization. The extractor can be trained to understand these variations and accurately extract the needed information.

The Machine Learning Extractor is a data extraction tool that uses machine learning models to extract data from various types of documents, such as invoices, receipts, or forms. It is especially useful when the same document type has multiple layouts or formats, as it can learn and infer the values for the targeted fields, even from documents and layouts it has never seen before1.

The Machine Learning Extractor can be used with one of UiPath’s public Document Understanding endpoints, which provide generic models for certain document types, or with custom trained machine learning models hosted in AI Center, which can be tailored to specific use cases. The Machine Learning Extractor can be configured and trained using the Data Extraction Scope activity in UiPath Studio2.
