Chapter 1: Introduction to Artificial Intelligence (AI)
🌟 What is Artificial Intelligence (AI)?
Artificial Intelligence (AI) is the branch of computer science that focuses on building smart machines capable of performing tasks that typically require human intelligence.
✅ Key Definition:
AI is the simulation of human intelligence in machines that are programmed to think, reason, learn, and make decisions.
🧭 Scope of AI
AI aims to solve real-world problems through automation, prediction, and reasoning. It includes fields such as:
-
Machine Learning
-
Natural Language Processing
-
Computer Vision
-
Robotics
-
Expert Systems
-
Speech and Voice Recognition
🕰️ Brief History of AI
| Year | Milestone |
|---|---|
| 1950 | Alan Turing proposes the Turing Test |
| 1956 | The term "Artificial Intelligence" coined at Dartmouth Conference |
| 1960s–70s | AI labs established; symbolic AI and expert systems |
| 1980s | Rise of Machine Learning and Neural Networks |
| 2000s | Big Data & Deep Learning boom |
| 2010s–2020s | AI in daily life (Siri, Google Assistant), Generative AI (ChatGPT, DALL·E) |
🧠 Types of Artificial Intelligence
| Type | Description | Example |
|---|---|---|
| 1. Narrow AI (Weak AI) | AI that specializes in one task only | Siri, Alexa, Google Maps |
| 2. General AI (Strong AI) | AI with human-level cognition & reasoning | Still theoretical |
| 3. Super AI | AI that surpasses human intelligence in all tasks | Hypothetical; future potential |
🎯 Goals of AI
-
Automation – Replace repetitive human work
-
Accuracy – Reduce human errors
-
Intelligence – Understand, learn, adapt
-
Decision-making – Provide better predictions & decisions
-
Human Interaction – Enable machines to communicate in natural language
🧬 Philosophy Behind AI
-
Can machines think like humans?
-
Should AI be allowed to make decisions?
-
How do we define consciousness in machines?
AI isn't just tech—it’s also deeply rooted in ethics, philosophy, and social impact.
