Introduction to AI 103

AI 103 is a beginner-level course that provides a broad introduction to the field of artificial intelligence. This article will provide an overview of the key topics covered in a typical AI 103 curriculum.

What is Artificial Intelligence?

Defining AI

Artificial intelligence, or AI, refers to computer systems that are designed to perform tasks that would otherwise require human intelligence. These include capabilities such as visual perception, speech recognition, decision-making, language translation, and more.

Goals of AI

The goals of AI research include developing systems that can:

  • Perceive their environment
  • Learn and improve
  • Reason and make decisions
  • Communicate and interact
  • Perform mechanical and creative tasks

Applications of AI

Today, AI is being applied across many industries and use cases:

  • Virtual assistants like Siri and Alexa
  • Recommendation systems on Netflix and Amazon
  • Self-driving car technologies
  • Fraud detection in finance
  • Personalized medicine
  • And more

As the technology advances, AI will transform how we work, communicate, and solve problems.

History of AI

Early Pioneers

  • Alan Turing introduced the Turing Test for evaluating machine intelligence in 1950.
  • John McCarthy coined the term “artificial intelligence” in 1955.
