• Question 112:

  Your company wants to reduce how long it takes for employees to log receipts in expense reports. All the receipts are in English.

  You need to extract top-level information from the receipts, such as the vendor and the transaction total. The solution must minimize development effort.

  Which Azure Cognitive Services service should you use?

  A. Custom Vision

  B. Personalizer

  C. Form Recognizer

  D. Computer Vision

  Correct Answer: C

  Azure Form Recognizer is a cognitive service that lets you build automated data processing software using machine learning technology. Identify and extract text, key/value pairs, selection marks, tables, and structure from your documents-the service outputs structured data that includes the relationships in the original file, bounding boxes, confidence and more.

  Form Recognizer is composed of custom document processing models, prebuilt models for invoices, receipts, IDs and business cards, and the layout model.

• Question 113:

  Your company uses an Azure Cognitive Services solution to detect faces in uploaded images. The method to detect the faces uses the following code.

  

  You discover that the solution frequently fails to detect faces in blurred images and in images that contain sideways faces.

  A. Use a different version of the Face API.

  B. Use the Computer Vision service instead of the Face service.

  C. Use the Identify method instead of the Detect method.

  D. Change the detection model. You need to increase the likelihood that the solution can detect faces in blurred images and images that contain sideways faces. What should you do?

  Correct Answer: D

  Evaluate different models.

  The best way to compare the performances of the detection models is to use them on a sample dataset. We recommend calling the Face - Detect API on a variety of images, especially images of many faces or of faces that are difficult to see,

  using each detection model. Pay attention to the number of faces that each model returns.
