Fundamental Conundrums of Artificial Intelligence
Intelligent agents have limited resources.
Computation is local, but problems have global constraints.
Logic is deductive, but many problems are not.
The world is dynamic, but knowledge is limited.
Problem solving, reasoning, and learning are complex, but explanation and justification are even more complex.
Characteristics of AI Problems
Knowledge often arrives incrementally.
Problems exhibit recurring patterns.
Problems have multiple levels of granularity.
Many problems are computationally intractable.
The world is dynamic, but knowledge of the world is static.
The world is open-ended, but knowledge is limited.
Characteristics of AI Agents
Agents have limited computing power.
Agents have limited sensors.
Agents have limited attention.
Computational logic is fundamentally deductive.
AI agents knowledge is incomplete relative to the world.
Which of these are AI problems?
Answering questions on Jeopardy.
Configuring the dimensions for the basement of a new house.
Tying shoelaces.
Deciding on a route to a new destination.
Making sense of a news broadcast.
Designing a robot that walks on water.
Establishing whether a flower pot can be used as a drinking cup.
Deciding whether or not a new animal is a bird.

What are cognitive systems?
Cognitive: dealing with human-like intelligence.
Systems: multiple interacting components such as learning, reasoning, and memory.
Cognitive Systems: Systems that exhibit human-like intelligence through processes like learning, reasoning, and memory.
