Artificial Intelligence

Artificial Intelligence (AI) is a branch of computer science that aims to create 
intelligent machines capable of performing tasks that typically require human intelligence.

The term "Artificial Intelligence" was coined by John McCarthy in 1956 at the 
Dartmouth Conference. This conference is widely considered the birthplace of AI as a field.

Types of AI:
- Narrow AI (Weak AI): Designed for specific tasks like voice recognition or playing chess
- General AI (Strong AI): Hypothetical AI with human-like general intelligence
- Superintelligent AI: Hypothetical AI surpassing human intelligence in all domains

Machine Learning is a subset of AI that enables systems to learn from data without 
being explicitly programmed. Deep Learning is a subset of Machine Learning using 
neural networks with multiple layers.

Key milestones in AI history:
- 1950: Alan Turing proposed the Turing Test for machine intelligence
- 1997: IBM's Deep Blue defeated world chess champion Garry Kasparov
- 2011: IBM Watson won Jeopardy! against human champions
- 2016: Google DeepMind's AlphaGo defeated Go world champion Lee Sedol
- 2022: ChatGPT was released by OpenAI, demonstrating advanced language capabilities

Neural networks are computing systems inspired by biological neural networks in 
the brain. They consist of interconnected nodes (neurons) organized in layers.

Common applications of AI include:
- Natural Language Processing (NLP) for text and speech understanding
- Computer Vision for image and video analysis
- Autonomous vehicles and robotics
- Medical diagnosis and drug discovery
- Recommendation systems for content and products

The AI winter refers to periods of reduced funding and interest in AI research. 
The first AI winter occurred from 1974 to 1980, and the second from 1987 to 1993.
