   Explanation

   Box 1: Classification - Incorrect Answers: An object detection project is for detecting which objects, if any, from a set of candidates are present in an image. Box 2: Multiclass - A multiclass classification project is for classifying images into a set of tags, or target labels. An image can be assigned to one tag only. Incorrect Answers: A multilabel classification project is similar, but each image can have multiple tags assigned to it. Box 3: General - General: Optimized for a broad range of image classification tasks. If none of the other specific domains are appropriate, or if you're unsure of which domain to choose, select one of the General domains.

5. Question 125 · 328 in bank

   Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You build a language model by using a Language Understanding service. The language model is used to search for information on a contact list by using an intent named FindContact. A conversational expert provides you with the following list of phrases to use for training. ✑ Find contacts in London. ✑ Who do I know in Seattle? ✑ Search for contacts in Ukraine. You need to implement the phrase list in Language Understanding. Solution: You create a new pattern in the FindContact intent. Does this meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: A

   Explanation

   Using a pattern could be a good solution IMHO... ✑ Find contacts in London. ✑ Who do I know in Seattle? ✑ Search for contacts in Ukraine. Like Where is {FormName}[?] Who authored {FormName}[?] {FormName} is published in French[?] (taken from https://docs.microsoft.com/en-us/azure/cognitive-services/luis/luis-concept-patterns) we could do: ✑ Find contacts in {CityOrCountry}. ✑ Who do I know in {CityOrCountry}[?] ✑ Search for contacts in {CityOrCountry}[?]. So, to me a pattern is a Solution (A)

6. Question 126 · 328 in bank

   You are building a conversational language understanding model. You need to enable active learning. What should you do?

   • AAdd show-all-intents=true to the prediction endpoint query.
   • BEnable speech priming.
   • CAdd log=true to the prediction endpoint query.
   • DEnable sentiment analysis.

   Show answer

   Answer: C

   Explanation

   C is the correct answer. "To enable active learning, you must log user queries. This is accomplished by calling the endpoint query with the log=true query string parameter and value." https://docs.microsoft.com/en-us/azure/cognitive-services/LUIS/how-to/improve-application#log-user-queries-to-enable-active-learning

8. Question 128 · 328 in bank

   You are building a Language Understanding model for an e-commerce platform. You need to construct an entity to capture billing addresses. Which entity type should you use for the billing address?

   • Amachine learned
   • BRegex
   • CgeographyV2
   • DPattern.any
   • Elist

   Show answer

   Answer: A

   Explanation

   My guess is A. An ML entity can be composed of smaller sub-entities, each of which can have its own properties. For example, Address could have the following structure: Address: 4567 Main Street, NY, 98052, USA Building Number: 4567 Street Name: Main Street State: NY Zip Code: 98052 Country: USA

9. Question 129 · 328 in bank

   You need to upload speech samples to a Speech Studio project for use in training. How should you upload the samples?

   • ACombine the speech samples into a single audio file in the .wma format and upload the file.
   • BUpload a .zip file that contains a collection of audio files in the .wav format and a corresponding text transcript file.
   • CUpload individual audio files in the FLAC format and manually upload a corresponding transcript in Microsoft Word format.
   • DUpload individual audio files in the .wma format.

   Show answer

   Answer: B

   Explanation

   , the best option is B. Upload a .zip file that contains a collection of audio files in the .wav format and a corresponding text transcript file. This method provides a balance of audio quality (with .wav files) and organization (having audio and transcripts together), which is essential for efficient and accurate training of speech recognition models.
