Azure Pre-Trained Models

Introduction

• Azure offers a range of pre-trained models through its various AI and machine learning services.
• These models are designed to help developers quickly and easily integrate AI capabilities into their applications without needing extensive knowledge of machine learning.

1. Azure Cognitive/AI Services
   • Azure Cognitive Services provide a variety of APIs that leverage pre-trained models for different AI capabilities. Here are some of the major services:

• Vision:
  • Computer Vision: Extracts information from images and videos, including object detection, optical character recognition (OCR), and image classification.
  • Custom Vision: Allows you to train your own image classification or object detection models with your data.
  • Face: Detects and recognizes faces in images, including facial attributes such as age, emotion, and gender.
• Speech:
  • Speech to Text: Converts spoken language into text.
  • Text to Speech: Converts text into spoken audio.
  • Speech Translation: Translates spoken language in real-time.
• Language:
  • Text Analytics: Analyzes text to extract key phrases, sentiment, entities, and language.
  • Translator: Provides text translation across multiple languages.
  • Language Understanding (LUIS): Allows you to create custom natural language understanding models to recognize intents and entities in user conversations.
  • QnA Maker: Builds a question and answer layer over your data to create a conversational FAQ experience.
• Decision:
  • Personalizer: Provides personalized content and experiences based on user behavior.

1. Azure Machine Learning
   • Azure Machine Learning is a comprehensive suite for building, training, and deploying machine learning models.
   • It also offers pre-trained models through its Model Gallery:

• Designer:
  • A drag-and-drop interface to create machine learning models without writing code.
  • It includes many pre-built components and modules for common machine learning tasks.
• Automated Machine Learning (AutoML):
  • Automatically trains and tunes models for you based on your dataset and problem type.

1. Azure Bot Services
   • Azure Bot Services, integrated with Microsoft Bot Framework, provides pre-trained models for building conversational agents (chatbots) that can understand and respond to user input.
2. Azure OpenAI Service
   • Azure offers access to OpenAI’s powerful models, including GPT-3, for generating natural language text based on the input provided.
   • This service enables you to build advanced AI applications such as chatbots, content generation tools, and more.
