1. Artificial Intelligence (AI)

Definition:
Artificial Intelligence (AI) is the broad field of creating systems that perform tasks requiring human intelligence.

Goal

Make machines capable of intelligent decision-making.

Examples

β™Ÿ Chess-playing programs
πŸš— Self-driving cars
🎀 Voice assistants
πŸ’¬ Chatbots
😊 Face recognition

2. Machine Learning (ML)

Machine Learning is a subset of AI. Instead of manually writing every rule, the computer learns patterns from data.
