What is AI?

1
Q

What is Artificial Intelligence?

A

AI is the study of creating machines that think, learn, and act rationally. There are two approaches:

  • human-centered AI (mimicking human cognition)
  • rational AI (optimal decision-making).

What is rationality in AI?

A

AI should be rational by making decisions that maximize success.

Human-centered approach: Observing human behavior to model intelligence.

Rationalist approach: Using logic and mathematics to define AI decision-making.

Q

The Turing test & total Turing test

A

Turing test: A machine is intelligent if a human cannot distinguish it from another human in conversation.

Total turing test: Adds perception (computer vision) and manipulation (robotics) as extra challenges.

In Depth Q. The Turing Test has been criticized as an insufficient measure of intelligence. What are some key objections to it?

A

Chinese Room argument (Searle) – a machine could pass the test without truly understanding.
Consciousness issue – intelligence might require subjective experiences.
Behavior vs. Thought – passing the test proves imitation, not real thinking.

Q

What is the definition of intelligence according to John McCarthy?

A

The computational part of the ability to achieve goals in the world

McCarthy’s definition links intelligence to goal achievement.

24
Q

What does the term ‘artificial’ imply in the context of intelligence?

A

Non-biological, constructed by humans

The term distinguishes between biological and non-biological forms of intelligence.

25

A

Every aspect of learning or any other feature of intelligence can in principle be so precisely defined that a machine can be made to simulate it

A

Exaggerated claims about AI capabilities

Hype can create unrealistic expectations about what AI can achieve.

30
Q

According to the text, what is a common skepticism regarding AI?

A

Too much hype, too less achieved

This reflects a critical view on the actual progress made in AI compared to public perception.

31
Q

What is AI as a field of research?

A

AI is part of Cognitive Science.

32
Q

Why is Cognitive Science considered a collaborative/interdisciplinary field?

A

Understanding the mind/brain may be too difficult for a single discipline in isolation.

33
Q

What do researchers in cognitive science seek to understand?

A

Brain processes as computational systems which manipulate representations.

34
Q

What does the computational theory of mind propose?

A

The mind stores symbolic representations and manipulates them via syntactic operations.

35
Q

How do cognitive scientists view the human mind?

A

As a complex system that receives, stores, retrieves, transforms, and transmits information.

36
Q

What is the issue with the fragmentation of AI research?

A

Researchers don’t always have the same goals or ideas.

37
Q

How are big AI questions approached in research?

A

They are often viewed from different perspectives and fields.

38
Q

What was the trend in AI hype from 1980 to 1996?

A

AI hype started in 1980 and went down in 1996 due to slow development and high costs.

39
Q

What happened to machine learning hype during the decline of AI hype?

A

Machine learning hype went up.

40
Q

What research area gained attention as AI hype declined?

A

Neural networks gained attention as more research was done on how they worked.

41
Q

Fill in the blank: Cognitive scientists view the human mind as a complex system that _______.

A

receives, stores, retrieves, transforms, and transmits information.

42
Q

True or False: Most AI research tackles the big AI questions directly.

43
Q

What is a consequence of the fragmentation of AI research?

A

Most research is just done on a little part of the big question.

44
Q

What was the trend for expert systems during the AI hype decline?

A

Expert systems went down.

45
Q

What is a primary focus for further AI research based on neural networks?

A

Modeling after the human brain.

46
Q

What is Strong AI?

A

Goal: To understand the human mind/brain as a computational device.
Specific: Focused on the human mind and replicating its functions.
General: Humans can solve a wide range of problems.
Belief: Machines can be built with thought, emotions, and human-like reasoning.

47
Q

How does Weak AI differto Strong AI in its approach?

A

It aims to solve problems using AI, without necessarily replicating human-like intelligence.

48
Q

What is Weak AI?

A

Goal: To develop intelligent machines that solve problems but are not necessarily human-like.
General: Can involve any AI technique or problem-solving approach.
Specific: Typically focuses on one task (e.g., vision, machine learning).
Doesn’t focus on theories of intelligence—only cares about solving problems.

49
Q

Why is Strong AI considered “specific” while Weak AI is “general”?

A

Strong AI is specific because it focuses on human intelligence only.
Weak AI is general because it considers any type of AI technique.

50
Q

In Depth Q. Could Weak AI eventually lead to Strong AI? Why or why not?

A

Some argue that advancing weak AI could accumulate knowledge and eventually lead to Strong AI.

Others believe Weak AI lacks consciousness and true understanding, making Strong AI impossible.

51
Q

In Depth Q. Which AI approach (Strong or Weak) is more useful today? Why?

A

Weak AI is more useful today because it powers real-world applications like chatbots, self-driving cars, and recommendation systems.
Strong AI is still a theoretical concept, with no known implementations.

52
Q

What is AI as Science?

A

Goal: Reverse-engineer the human mind/brain.
The object of interest exists in nature (e.g., studying human intelligence).
AI as a science might fail if it cannot fully understand human intelligence.
Depends on humans to study and model intelligence.

53
Q

What is AI in Engineering?

A

Goal: Engineer clever machines, regardless of human cognition.
The object of interest is unknown and must be discovered or created.
AI as engineering has already succeeded in applications like automation and robotics.
Independent of humans—focuses on solving problems, not replicating human thought.

54
Q

What is an example of AI as science?

A

Studying how neurons in the brain work to create biologically inspired AI.

55
Q

What is an example of AI as engineering?

A

Creating self-driving cars or AI-powered robots without human-like reasoning.

56
Q

In Depth Q. Can AI as engineering exist without AI as science? Why or why not?

A

AI as engineering can succeed without science because it focuses on practical solutions (e.g., speech recognition, computer vision).
However, AI science helps improve AI engineering by advancing understanding of cognition and learning processes.

57
Q

In Depth Q. Why is AI as science considered more uncertain than AI as engineering?

A

AI as science depends on whether human intelligence can be fully understood—which is still unknown.
AI as engineering already works because machines solve tasks without requiring human-like thought.
