COSC Computer Science: Chapter 15
Artificial Intelligence
Artificial intelligence (AI) - correct answer - The intelligence of machines and the branch of
computer science that aims to create it
- The study and design of intelligent agents (as system that perceives its environment and takes
actions that maximize its chances of success)
Turing's theory of computation - correct answer a machine, by shuffling symbols could simulate
any conceivable act of mathematical deduction.
We need not decide if a machine can think. We need only decide if a machine can act as
intelligently as a human being
Desirable Traits of AI - correct answer • Deduction, reasoning, problem-solving • Knowledge
representation • Planning • Learning • Natural language processing • Motion and manipulation
• Perception • Social intelligence • Creativity • General intelligence
The Turing Test - correct answer allows a human to interrogate two entities, both hidden from
the interrogator.
The objective is to be unable to distinguish between the two beyond random chance.
Can you tell if you are interrogating a machine or a human?
Artificial neural networks - correct answer Can be created by simulating individual neurons in
hardware and connecting them in a massively parallel network of simple devices
Neural network - correct answer - Can learn from experience by modifying the weights on its
connections
- Can be given an initial set of weights and thresholds that is simply a first guess
- Network is then presented with training data
