History of AI

AI’s journey from concept to application spans several decades and milestones:

1. Early Foundations (1940s-1950s)

• Alan Turing, a pioneer of modern computing, introduced the idea of machines capable of “thinking.”
• The Turing Test was proposed to assess a machine’s ability to exhibit human-like intelligence.
• Researchers began experimenting with symbolic reasoning and basic problem-solving programs.

2. The Birth of AI (1956)

• AI was officially recognized as a field of study during the Dartmouth Conference.
• Early programs focused on symbolic reasoning, such as playing games or solving mathematical theorems.

3. The First AI Winter (1970s)

• High expectations led to disappointment due to technological and computational limitations.
• Funding decreased, and interest in AI research waned.

4. Revival and Expert Systems (1980s)

• The rise of expert systems, which relied on rule-based approaches, revived interest in AI.
• These systems were used in industries like healthcare and manufacturing for decision support.

5. Machine Learning Era (1990s-2000s)

• Advances in machine learning (ML) allowed AI to learn from data.
• IBM’s Deep Blue defeated chess champion Garry Kasparov in 1997, marking a significant milestone.
• AI began finding applications in finance, e-commerce, and search engines.

6. Modern AI Revolution (2010s-Present)

• Breakthroughs in deep learning, powered by neural networks, led to state-of-the-art performance in tasks like image and speech recognition.
• Examples include Google’s AlphaGo, ChatGPT, and self-driving cars.
• AI is now widely applied in industries like healthcare, retail, entertainment, and beyond.

Definition and Examples of AI

Definition: AI is the branch of computer science that aims to create machines capable of performing tasks that require intelligence, such as reasoning, learning, perception, and decision-making.
