AI-102 Free Dumps Questions And Answers To Prepare You For The Exam:
AI-102 exam dumps questions are available online and are valuable for your exam study.
Q- 1
DRAG DROP You are building a retail chatbot that will use a QnA Maker service. You upload an internal support document to train the model. The document contains the following question: “What is your warranty period?”
Users report that the chatbot returns the default QnA Maker answer when they ask the following question: “How long is the warranty coverage?” The chatbot returns the correct answer when the users ask the following question: \\’What is your warranty period?” Both questions should return the same answer.
You need to increase the accuracy of the chatbot responses. Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order. (Choose three.)
Select and Place:
Correct Answer:
Step 1: Add alternative phrasing to the question and answer (QnA) pair.
Add alternate questions to an existing QnA pair to improve the likelihood of a match to a user query.
Step 2: Retrain the model.
Periodically select Save and train after making edits to avoid losing changes.
Step 3: Republish the model
Note: A knowledge base consists of question and answer (QnA) pairs. Each pair has one answer and a pair contains all the information associated with that answer.

Q- 2
DRAG DROP
You are developing a photo application that will find photos of a person based on a sample image by using the Face API. You need to create a POST request to find the photos.
How should you complete the request? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:
Box 1: detect
Face – Detect With Url: Detect human faces in an image, return face rectangles, and optionally with faceIds, landmarks, and attributes. POST {Endpoint}/face/v1.0/detect
Box 2: matchPerson
Find similar has two working modes, “matchPerson” and “matchFace”. “matchPerson” is the default mode that it tries to find faces of the same person as possible by using internal same-person thresholds. It is useful to find a known person\\’s other photos. Note that an empty list will be returned if no faces pass the internal thresholds. “matchFace” mode ignores same-person thresholds and returns ranked similar faces anyway, even the similarity is low. It can be used in the cases like searching celebrity-looking faces.

Q- 3
You have the following C# method for creating Azure Cognitive Services resources programmatically.
You need to call the method to create a free Azure resource in the West US Azure region. The resource will be used to generate captions of images automatically. Which code should you use?
A. create_resource(client, “res1”, “ComputerVision”, “F0”, “westus”)
B. create_resource(client, “res1”, “CustomVision.Prediction”, “F0”, “westus”)
C. create_resource(client, “res1”, “ComputerVision”, “S0”, “westus”)
D. create_resource(client, “res1”, “CustomVision.Prediction”, “S0”, “westus”)
Correct Answer: B
Many of the Cognitive Services have a free tier you can use to try the service. To use the free tier, use F0 as the SKU for your resource. There are two tiers of keys for the Custom Vision service. You can sign up for a F0 (free) or S0 (standard) subscription through the Azure portal.
Incorrect Answers:
A: There is no free tier (F0) for ComputerVision.
