Upload to: An Azure Storage account
Model type: Custom neural
You have 1,000 scanned hand-written survey responses with no consistent layout. The goal is to extract data while minimizing development effort.
Step 1: Upload location
For Azure AI Document Intelligence (formerly Form Recognizer), training data (images, PDFs) must be placed in a container in an Azure Storage account.
Options like Cosmos DB or Azure Files share are not valid training data sources for Document Intelligence.
Therefore, you upload the survey images to Azure Storage account.
Step 2: Model type
The surveys are handwritten and do not have a consistent layout.
Custom template models work only when the layout is fixed and consistent (e.g., invoices with the same fields in the same place).
Identity document (ID) model is a prebuilt model for passports, driver's licenses, etc., not for surveys.
Custom neural model is designed to handle unstructured or variable-layout forms, including handwritten content. This best fits the survey scenario.
Thus, the correct configuration is:
Upload to Azure Storage account
Use Custom neural model
The answer:
Upload to: An Azure Storage account
Model type: Custom neural
