Artificial Intelligence Artificial intelligence (AI) - the science of making machines imitate human thinking and behavior. Robot - mechanical device equipped with simulated human senses and the capability of taking action on its own. 4-21 Management Information Systems for the Information Age

Artificial Intelligence The AI systems that businesses use most can be classified into four categories: Expert systems Neural networks Genetic algorithms Intelligent agents 4-22 Management Information Systems for the Information Age

Management Information Systems for the Information Age Expert Systems Expert system, or knowledge-based system - artificial intelligence system that applies reasoning capabilities to reach a conclusion. 4-23 Management Information Systems for the Information Age

Expert Systems Components of an Expert System Expert systems are good for diagnostic (what’s wrong?) and prescriptive (what to do?) problems. 4-24 Management Information Systems for the Information Age

Expert Systems Components of an Expert System An expert system combines information, people, and IT components. Information types include: Domain expertise – the reasoning process that will solve the problem. “Why” information. Problem facts. 4-25 Management Information Systems for the Information Age

Expert Systems Components of an Expert System 4-26 Management Information Systems for the Information Age

Expert Systems Components of an Expert System People Domain expert - provides the domain expertise in the form of problem-solving strategies. Knowledge engineer – IT specialist who formulates the domain expertise into an expert system. Knowledge worker or user - that’s you. 4-27 Management Information Systems for the Information Age

Expert Systems Components of an Expert System IT Components Knowledge base - stores the rules of the expert system. Knowledge acquisition – used to enter the rules. Inference engine - takes the problem facts and searches the knowledge base for rules that fit. User interface – used to run the consultation. Explanation module – where information is stored. 4-28 Management Information Systems for the Information Age

Expert Systems What Expert Systems Can and Can’t Do An expert system can: Reduce errors Improve customer service Reduce costs An expert system can’t: Use common sense Automate all processes On Your Own Traffic Lights Revisited (p. 199) 4-29 Management Information Systems for the Information Age

Management Information Systems for the Information Age Neural Networks Neural network (often called an artificial neural network or ANN) - an artificial intelligence system that is capable of finding and differentiating patterns. 4-30 Management Information Systems for the Information Age

Neural Networks Types of Neural Networks Self-organizing neural network - finds patterns and relationships in vast amounts of data by itself. Back-propagation neural network - a neural network trained by someone. Team Work How Would You Classify People? (p. 202) 4-31 Management Information Systems for the Information Age
