I) Artificial Intelligence (AI)

Artificial Intelligence

Artificial Intelligence (AI) is a rapidly evolving field of technology that aims to create machines capable of intelligent behavior and decision-making, mimicking human cognitive functions such as learning, problem-solving, and understanding natural language.

1. Origin and Evolution

The concept of AI can be traced back to ancient times, with philosophical and mythological tales of artificial beings coming to life. Stanford researcher examines earliest concepts of artificial intelligence, robots in ancient myths. However, the modern inception of AI as a formal academic discipline began during a workshop at Dartmouth College in 1956. Here, scholars explored how “every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.”

2. AI Today

AI is now part of our daily lives, often in ways we may not even realize. Applications like voice assistants (e.g., Siri, Alexa), recommendation systems (e.g., Netflix, Spotify), and language translation (e.g., Google Translate) all rely on AI.
