Introduction to Microsoft Azure AI Fundamentals
Artificial Intelligence (AI) is transforming industries by enabling machines to perform tasks that traditionally required human intelligence. Microsoft Azure AI is a powerful cloud-based platform that provides tools and services for developing, training, and deploying AI solutions.
The Microsoft Azure AI Fundamentals (AI-900) certification is designed for individuals who want to understand AI concepts and how Azure implements them. This guide explores Azure AI fundamentals, key services, and practical applications.
2. Understanding Artificial Intelligence (AI) and Machine Learning (ML)
What is AI?
AI refers to the simulation of human intelligence in machines. It includes:
- Machine Learning (ML): Algorithms that learn from data.
- Deep Learning: A subset of ML using neural networks.
- Natural Language Processing (NLP): Enables machines to understand human language.
Difference Between AI and ML
- AI is the broader concept of machines performing intelligent tasks.
- ML is a technique used to achieve AI by training models on data.
