UiPath Document Understanding and AI Center Flashcards

What is UiPath AI Center primarily used for?

Answer: Deploying, managing, and retraining ML models used inside automation workflows

AI Center is a UiPath platform component that hosts ML models as skills, manages training pipelines, and tracks model performance over time.

In UiPath AI Center, what is an 'ML Skill'?

Answer: A deployed ML model exposed as an API endpoint callable from UiPath Studio activities

An ML Skill wraps a trained ML model as a REST API endpoint that Studio's 'ML Skill' activity can call to get predictions inline in automation.

What does the confidence score returned by a Document Understanding extractor represent?

Answer: The model's estimated probability that the extracted field value is correct

Confidence scores (0–1) reflect how certain the AI model is about each extracted value, guiding whether human review is needed.

In Document Understanding, which activity extracts specific field values from a classified document?

Answer: Extract Document Data

The 'Extract Document Data' activity (within the Data Extraction Scope) applies extractors to pull field values from the classified document.

Which UiPath component enables continuous ML model improvement by routing low-confidence extractions back for human labeling?

Answer: AI Center's Active Learning pipeline

AI Center's Active Learning loop collects human-validated corrections from Validation Station and uses them to retrain models over time.

What file formats does UiPath Document Understanding natively support for document ingestion?

Answer: PDF, PNG, JPG, TIFF, and other common document and image formats

Document Understanding supports PDFs (native and scanned) as well as raster image formats like PNG, JPG, BMP, and TIFF for OCR-based processing.
