Lesson 1 - Intro to KBAI

Question 1

What are the 5 main conundrums in AI?

Answer 1

1) Intelligent agents have limited resources (eg compute)
2) Computation is local, but problems have global constraints
3) Logic is deductive, but many problems are not
4) The world is dynamic, but knowledge is limited
5) Problem solving, reasoning, and learning are complex, but explanation and justification are even more complex.

Question 2

What are the 6 characteristics of AI Problems?

Answer 2

1) Knowledge often arrives incrementally
2) Problems exhibit recurring patterns
3) Problems have multiple levels of granularity
4) Many problems are computationally intractable
5) The world is dynamic, but knowledge of the world is static
6) The world is open-ended, but knowledge is limited

Question 3

What are the 5 characteristics of AI Agents?

Answer 3

1) Agents have limited computing power
2) Agents have limited sensors
3) Agents have limited attention
4) Computational logic is fundamentally deductive
5) AI agent’s knowledge is incomplete relative to the world

Question 4

What is Knowledge-Based AI?

Answer 4

Fundamental Process of AI:

• Reasoning
• Learning
• Memory
• All interconnected*
• Also known as “Deliberation”.

Question 5

What are the 4 schools of AI?

Answer 5

1) Agents that think optimally (specialized) -> Machine Learning
2) Agents that think like humans (generally) -> Semantic Web
3) Agents that act optimally -> Airplane autopilot
4) Agents that act like humans -> Improvisational robots

Question 6

What are Cognitive Systems?

Answer 6

Systems that exhibit human-like intelligence through processes like learning, reasoning, and memory.
