Study Notes
Types of Artificial Intelligence
- Thinking Rationally: codifying "right thinking" processes, formal logic provides a precise notation and rules for representing and reasoning with all kinds of things in the world.
- Acting Rationally: acting to achieve one's goals, given one's beliefs, more general than the "laws of thought" approach.
Branches of AI
Search
- Problem-solving technique that systematically explores a space of problem states.
- Approaches: means-end analysis, iterative deepening, brute-force or blind search.
- Types of search algorithms: Breadth First Search, Depth First Search, Hill Climbing, etc.
Logical AI
- Represents knowledge of an agent's world, goals, and current situation by sentences in logic.
- Approaches:
- Fuzzy Logic: models reasoning that is imprecise in uncertain environments.
- Non-monotonic Logic: models beliefs in an environment of incomplete information, revising predictions when new observations are made.
Learning
- Machine learns whenever it changes its structure, program, or data to improve its expected future performance.
- Tasks: recognition, diagnosis, planning, robot control, prediction, etc.
Representation
- Central task in AI: representing knowledge.
- Five roles for knowledge representation:
- Representative inside the reasoner or a stand-in for the things that exist in the world.
- Acting as ontological commitments, restricting what we can see in the world and how detailed this perception is.
Areas of Artificial Intelligence
- Natural Language Processing: getting computers to communicate with us in human languages.
- Inference: getting computers to remember complicated interrelated facts and draw conclusions from them.
- Planning: getting computers to plan sequences of actions to accomplish goals.
- Expert Systems: getting computers to offer advice based on complicated rules for various situations.
- Vision: getting computers to look through cameras and see what's there.
- Robotics: getting computers to move themselves and objects.
Turing Test
- Measures the performance of an allegedly intelligent machine against that of a human being.
- Interrogator distinguishes the computer from the human on the basis of their answers.
