AI-102 Practice Question: A company uses Azure Form Recognizer to extract…
A company uses Azure Form Recognizer to extract data from invoices. The extracted data contains many errors for a specific vendor's invoices. What should they do?
⚠ Common exam trap
Many exam-takers assume increasing the confidence threshold (Option C) will fix extraction errors, but it only filters results rather than improving the underlying model's accuracy for vendor-specific formats.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Custom train a model with labeled examples of that vendor's invoices.
Azure Form Recognizer's prebuilt invoice model may not generalize well to vendor-specific layouts or data formats. By custom training a model with labeled examples of that vendor's invoices, you adapt the extraction to the unique fields, tables, and formatting, significantly reducing errors. This leverages the service's supervised learning capability to improve accuracy for domain-specific documents.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a different prebuilt model.
Why it's wrong here
Other prebuilt models may not cover invoices.
- ✗
Disable the OCR step.
Why it's wrong here
OCR is essential for text extraction.
- ✗
Increase the confidence threshold.
Why it's wrong here
May reduce errors but not address format.
- ✓
Custom train a model with labeled examples of that vendor's invoices.
Why this is correct
Custom model learns vendor-specific layouts.
