What is Artificial Intelligence (AI)?

Artificial Intelligence refers to the simulation of human intelligence in machines, enabling them to perform tasks that typically require human cognitive abilities such as learning, reasoning, problem-solving, perception, and decision-making.

Key Characteristics of AI:

• Learning: AI systems learn from data and improve over time.
• Reasoning: AI can analyze situations and make logical decisions.
• Problem-Solving: AI finds solutions to complex problems.
• Perception: AI can recognize images, speech, and patterns.
• Autonomy: AI operates independently in some scenarios.

A Brief History of AI

AI has evolved significantly over the decades. Here are key milestones:

• 1950s: Alan Turing proposed the "Turing Test" to determine if a machine can exhibit intelligent behavior.
• 1956: John McCarthy coined the term "Artificial Intelligence."
• 1970s-1980s: Expert systems (rule-based AI) became popular.
• 1997: IBM’s Deep Blue defeated world chess champion Garry Kasparov.
• 2011: IBM Watson won Jeopardy! against human champions.
• 2016: Google’s AlphaGo defeated the world’s best Go player.
• 2020s: AI is revolutionizing industries like healthcare, finance, and education.

Types of Artificial Intelligence

AI is categorized into different types based on its capabilities and functionality:

1. Based on Capabilities:

• Narrow AI (Weak AI): Designed for specific tasks (e.g., Siri, chatbots, recommendation systems).
• General AI (Strong AI): Hypothetical AI with human-like intelligence (not yet achieved).
• Super AI: AI surpassing human intelligence (theoretical and futuristic).

2. Based on Functionality:

• Reactive AI: Does not store past experiences (e.g., Deep Blue).
• Limited Memory AI: Learns from past data (e.g., self-driving cars).
• Theory of Mind AI: Hypothetical AI that understands emotions and human thoughts.
• Self-Aware AI: A futuristic AI that possesses its own consciousness.
