What is Artificial Intelligence?
Artificial Intelligence (AI) is the capability of a computer or robot controlled by a computer to perform tasks usually requiring human intelligence. AI is defined as:
An intelligent entity created by humans.
Capable of performing tasks intelligently without explicit instructions.
Capable of thinking and acting rationally and humanely.
History of Artificial Intelligence
The idea of AI dates back to ancient Greek myths of intelligent robots. The term “AI” was officially coined in 1956 at Dartmouth College by Marvin Minsky. AI has since seen significant milestones:
1943: Concept of a model mimicking brain cells introduced.
1950: Alan Turing’s test for machine intelligence.
1956: Term “Artificial Intelligence” coined.
1959: Machine learning concept introduced.
1963: First AI research lab at Stanford.
1966: First chatbot, ELIZA, created.
1972-1980: “AI winter” due to declining interest.
1980: AI resurgence with business applications.
1997: IBM’s Deep Blue defeats a world chess champion.
2002: AI used in household vacuum cleaners.
2005: US military uses robots.
2006: Big tech companies adopt AI.
2008: Google adds speech recognition to iPhone apps.
2011: IBM’s Watson wins a quiz show.
2012: Google’s project advances AI learning from videos.
2014: Google tests a self-driving car; Amazon launches Alexa.
2016: Robot Sophia introduced.
2020: AI accelerates COVID-19 vaccine research.
These events illustrate AI’s journey from concept to everyday utility.
How does Artificial Intelligence Work?
Building an AI system involves teaching a machine to think and act like humans, often better. Key components include:
Machine Learning (ML): Enables machines to make decisions based on past data.
Deep Learning: A subset of ML using layered analysis.
Neural Networks: Brain-like structures processing information.
Natural Language Processing (NLP): Helps machines understand and respond to human language.
Computer Vision: Allows machines to interpret images.
Cognitive Computing: Mimics human thought processes.
Types of Artificial Intelligence
AI is classified into three types based on capabilities:
Artificial Narrow Intelligence (ANI): Specialized in one task. Examples: Siri, Alexa.
Artificial General Intelligence (AGI): Human-like intelligence, yet theoretical.
Artificial Super Intelligence (ASI): Surpasses human intelligence, speculative and debated.
Purpose and Uses of AI
AI aims to enhance human capabilities and assist in complex decision-making, streamline operations, and automate tasks. It is widely used in:
Predictive search (Google)
Movie recommendations (Netflix)
Facial recognition (Facebook)
AI processes large amounts of data to optimize search, detect patterns, and predict outcomes.
Relationship Between AI, ML, and DL
AI encompasses ML and DL. ML emerged from AI and DL from ML, each advancing the previous technology.
Applications in Business
AI transforms industries reliant on data, optimizing operations across sectors like healthcare, finance, marketing, and entertainment.
