Study Notes
Minimizing Development Effort and Costs
- To minimize development effort and costs, use Face API, an AI service that analyzes faces in images.
- Face API allows for facial recognition in apps without requiring machine learning expertise.
Configuring Index Attributes for Azure Cognitive Search
- To include a category field in search results, ensure users can search for words in the category field, and enable drill-down filtering based on category, configure the category field with the following attributes:
- searchable
- facetable
- retrievable
Preparing a Custom Vision Model for Deployment
- To prepare a Custom Vision model for deployment on an Android app, perform the following actions in sequence:
Deployment Steps
- Change the model domain
- Retrain the model
- Export the model
Face Recognition API and Person Groups
- The Face Recognition API has the following subscription quotas:
- Free-tier: 1,000 person groups, each holding up to 1,000 persons
- S0-tier: 1,000,000 person groups, each holding up to 10,000 persons
Implementing Authentication and Active Learning
- To implement authentication for a bot, use Direct Line Speech, a robust end-to-end solution for creating a flexible voice assistant.
- Active learning suggestions allow improving the quality of a knowledge base by suggesting alternative questions based on user submissions.
Language Support for Emails and Direct Messages
- To process incoming email and direct messages in either French or English language support teams, use the Azure Cognitive Services API for language detection.
- The API endpoint for language detection is
/text/analytics/v3.1/languages.
