🔍 What is Artificial Intelligence (AI)?
Artificial Intelligence (AI) is a branch of computer science that aims to create machines or systems that can perform tasks that normally require human intelligence.
🧠 AI performs tasks like:
- Understanding language
- Recognizing images
- Making decisions
- Learning from data
- Solving problems
💡 Real-Life Examples of AI
| Area | Example of AI Use |
|---|---|
| Education | AI tutors, plagiarism checkers |
| Healthcare | Disease diagnosis, robotic surgery |
| Agriculture | Crop monitoring, soil analysis |
| Banking | Fraud detection, chatbots |
| Entertainment | Movie/music recommendations |
| Transportation | Self-driving cars, smart traffic signals |
🧭 Goals of AI
- Make machines think and act like humans
- Increase efficiency and accuracy
- Help solve complex problems
- Reduce human efforts in repetitive tasks
🧩 Difference Between Human Intelligence & AI
| Aspect | Human Intelligence | Artificial Intelligence |
|---|---|---|
| Learning | Learns from experience & emotions | Learns from data and training |
| Emotions | Has feelings | No emotions |
| Decision Making | Uses logic, experience, and emotions | Uses data, patterns, and algorithms |
| Creativity | Highly creative | Limited creativity (based on inputs) |
| Speed | Slower than computers | Extremely fast |
🧠 3 Domains of AI
1️⃣ Data Science (DS)
AI uses data to learn and make decisions.
- Example: YouTube suggesting videos based on your watch history.
2️⃣ Natural Language Processing (NLP)
Machines understanding, interpreting, and generating human language.
- Example: Alexa, Google Assistant, chatbots.
3️⃣ Computer Vision (CV)
AI understands and analyzes images, videos, and visual content.
- Example: Face recognition in smartphones, automatic tagging on Facebook.
