Origins of AI
Unlock Audio Lesson
Welcome class! Today, we delve into the origins of Artificial Intelligence. Can anyone tell me the year the term 'Artificial Intelligence' was first used?
Was it in the 1940s?
Close! It was actually coined in 1956 during the Dartmouth Conference, a pivotal moment in AI history. This conference set the stage for AI as a formal field of study.
What exactly happened at that conference?
Great question! The Dartmouth Conference gathered researchers to discuss AI's potential, laying down the foundational ideas that shaped the future of AI research. Remember, 'Dartmouth' is a key term, as it marks the beginning of structured AI exploration.
Symbolic AI and Expert Systems

Moving forward, can anyone explain what Symbolic AI is?
Isn't it about using symbols and rules to represent knowledge?
Exactly! In the 1960s to 80s, Symbolic AI and expert systems leveraged these concepts to devise solutions based on encoded human knowledge. It primarily focused on logical reasoning.
How does that differ from what we see today?
Good observation! Unlike the rule-based approaches of Symbolic AI, today’s AI systems like those based on machine learning learn from data patterns. We see a shift from predetermined rules to self-learning algorithms.
Evolution into Machine Learning

• 1956 – The term "Artificial Intelligence" coined at Dartmouth Conference
Detailed Explanation
In 1956, a conference at Dartmouth College marked the formal beginning of what we now call Artificial Intelligence (AI). During this event, leading researchers gathered to discuss and explore the potential of machines to exhibit human-like intelligence. The term 'Artificial Intelligence' was created during this conference, which helped to establish AI as a scientific field.
Examples & Analogies
Think of this conference as the big reveal of a new invention, like the launch of a smartphone. This event was crucial because it set the stage for all the innovations in AI that followed, just as the introduction of smartphones changed how we communicate and access information.

• 1960s–80s – Symbolic AI and expert systems
Detailed Explanation
From the 1960s to the 1980s, the focus in AI research shifted toward symbolic AI and expert systems. Symbolic AI involves using symbols to represent problems and logic to solve them. Expert systems were designed to mimic the decision-making abilities of a human expert in specific fields, such as medical diagnosis or legal reasoning. This era showcased early successes in AI applications.
Examples & Analogies
Imagine a recipe book that not only lists ingredients but also offers step-by-step guides on how to prepare dishes. Expert systems functioned similarly in specific domains, providing 'recipes' for solving complex problems based on established knowledge.

• 1990s – Emergence of machine learning and neural networks
Detailed Explanation
The 1990s saw a significant shift in AI, with the emergence of machine learning and neural networks. Rather than relying solely on programmed rules, systems began to learn from data. This period marked the development of algorithms that enable computers to improve their performance as they are exposed to more information. Neural networks, inspired by the human brain, became a pivotal technology, allowing for more sophisticated data processing.
Examples & Analogies
Think of this like teaching a dog tricks. Initially, you might use commands and rewards (rules), but over time, the dog learns from experience. Similarly, machine learning algorithms learn from patterns in data and improve their accuracy over time.
