1. Understanding AI from a Developer’s Perspective

Artificial Intelligence is a broad discipline focused on enabling machines to perform tasks that typically require human intelligence. For developers, AI is not just theory. It is code, data, algorithms, infrastructure, and measurable impact.

AI includes multiple subfields:

• Machine Learning
• Deep Learning
• Natural Language Processing
• Computer Vision
• Reinforcement Learning
• Generative AI
• Knowledge Representation
• AI Ethics and Responsible AI

Developers must understand AI at three levels:
