   Explanation

   NNY is the answer. https://learn.microsoft.com/en-us/azure/cognitive-services/language-service/entity-linking/overview Entity linking is one of the features offered by Azure Cognitive Service for Language, a collection of machine learning and AI algorithms in the cloud for developing intelligent applications that involve written language. Entity linking identifies and disambiguates the identity of entities found in text. For example, in the sentence "We went to Seattle last week.", the word "Seattle" would be identified, with a link to more information on Wikipedia.

   You train a Conversational Language Understanding model to understand the natural language input of users. You need to evaluate the accuracy of the model before deploying it. What are two methods you can use? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

   • AFrom the language authoring REST endpoint, retrieve the model evaluation summary.
   • BFrom Language Studio, enable Active Learning, and then validate the utterances logged for review.
   • CFrom Language Studio, select Model performance.
   • DFrom the Azure portal, enable log collection in Log Analytics, and then analyze the logs.

   Show answer

   Answer: AC

   Explanation

   agree with SmallFire: Active Learning cannot be initiated prior to the deployment of the model. The primary purpose of the 'Active Learning' feature is to leverage actual user interaction data to enhance the model's understanding capabilities. This is a continuous learning and optimization process that takes place after the model has been deployed and put into actual use. so the answer is AC.

6. Question 156 · 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 develop an application to identify species of flowers by training a Custom Vision model. You receive images of new flower species. You need to add the new images to the classifier. Solution: You create a new model, and then upload the new images and labels. Does this meet the goal?

   • AYes
   • BNo

   Show answer

   Answer: B

   Explanation

   No. If "You create a new model, and then upload the new images and labels." your model lacks previous images of other flowers. So the answer is correct.

   1. SpeechRecognitionLanguage 2. AddTargetLanguage https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/how-to-translate-speech?tabs=terminal&pivots=programming-language-csharp#change-the-source-language One common task of speech translation is specifying the input (or source) language. In your code, interact with the SpeechTranslationConfig instance by assigning it to the SpeechRecognitionLanguage property: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/how-to-translate-speech?tabs=terminal&pivots=programming-language-csharp#add-a-translation-language Another common task of speech translation is to specify target translation languages. At least one is required, but multiples are supported. With every call to AddTargetLanguage, a new target translation language is specified. In other words, when speech is recognized from the source language, each target translation is available as part of the resulting translation operation.

   Explanation

   https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/custom-speech-overview#how-does-it-work With Custom Speech, you can upload your own data, test and train a custom model, compare accuracy between models, and deploy a model to a custom endpoint. - Create a project and choose a model. Use a Speech resource that you create in the Azure portal. If you will train a custom model with audio data, choose a Speech resource region with dedicated hardware for training audio data. - Upload test data. Upload test data to evaluate the speech to text offering for your applications, tools, and products. - Train a model. Provide written transcripts and related text, along with the corresponding audio data. Testing a model before and after training is optional but recommended. - Deploy a model. Once you're satisfied with the test results, deploy the model to a custom endpoint. With the exception of batch transcription, you must deploy a custom endpoint to use a Custom Speech model.
