  1. 0 DSS: Decision Support Systems and AI: Artificial Intelligence In Business

  2. AI in Business I’m ready to do some business Some Commercial Applications • Decision Support • Expert Systems • Information Retrieval • Virtual Reality • Robotics

  3. Overview of AI Goal of AI develop computer systems that exhibit intelligence or simulate the ability to think AI pioneered by Computer Science But, AI involves a combination of Computer Science, Biology, Psychology, Linguistics, Mathematics,Engineering

  4. What really is Intelligence? • Specifically, what are the signs of Intelligent Behavior? • Think about it for a while

  5. Which of the following is the best example of intelligent behavior? 10 • Ability to add numbers • Ability to see and recognize objects • Ability to adapt to surroundings • Ability to learn for mistakes

  6. What really is Intelligence? 0 • You are about to start an online chat (IM) with two entities: • One entity is a human • The other is a computer • After hours of conversation, you can not tell which entity is a computer. • Does this mean the computer is Intelligent?

  7. Intelligent Behavior 0 • What are some of the signs, attributes, or characteristics of Intelligent Behavior

  8. Characteristics of Intelligent Behavior 0 • Learn from experience & apply the knowledge • Computer can automatically improve performance based on Experience • Machine Learning • Computational Learning

  9. Characteristics of Intelligent Behavior 0 • Handle complex situations • Computer Systems can often handle complexity better than humans • Consider a process control system that must simultaneous track 100 different system variables.

  10. Characteristics of Intelligent Behavior 0 • Solve problems when important information is missing • Computer Systems can find patterns and deal with all sorts of missing information

  11. Characteristics of Intelligent Behavior 0 • React quickly & correctly to new situations; Acquire & Apply Knowledge • Here is where computers start to fail. • Adapting to completely new situations is a problem for computer systems. • Its very difficult to design a computer system that can combine, connect, and acquire knowledge to solve completely new problems

  12. Characteristics of Intelligent Behavior 0 • Determine what is important. • Exhibit creativity and imagination • Process visual information efficiently • Use reason to solve problems • These are some other Characteristics that humans possess. • Computer systems have a lot of catching up to do.

  13. Which of the following do computer need to catch up on? 10 • Determine what is important. • Exhibit creativity and imagination • Process visual information efficiently • Use reason to solve problems

  14. AI in Business • AI continues to improve and evolve. • Scientists and Engineers are pushing the envelope of what is possible. • In Business, there is a better understanding of the capabilities of Intelligent Computer Systems • It is important to know which types of problems are suited for humans, and which are suited for Computers.

  15. Human Intelligence vs. AI

  16. Human Intelligence vs. AI

  17. AI: Application Domains

  18. AI: Commercial Domains 0 • Decision Support • Integrating the advantages of AI with Human Intelligence. • More intelligent Interfaces • More intelligent processing for massive data

  19. AI: Commercial Domains 0 • Information Retrieval • Automatic simplification for massive data • Natural language technology: computer can speak our language.

  20. AI: Commercial Domains • Virtual Reality • Better training environment from pilots to doctors • Robotics • Bringing the precision and speed of computers into the physical world • Goes beyond manufacturing and assembly lines; Baggage Inspection, Bomb Removal, Replacement Limbs.

  21. Expert Systems • The idea is to inject expert knowledge in to a computer system. • The primary purpose is to automate decision making. • The decision environments have structure • The alternatives and goals are often established in advance.

  22. Expert Systems vs. DSS Expert System Inject expert knowledge in to a computer system. Automate decision making. The decision environments have structure The alternatives and goals are often established in advance. The expert system can eventually replace the human decision maker. Decision Support System Extract or gain knowledge from a computer system Facilitates decision making Unstructured environment Alternatives may not be fully realized yet Use goals and the system data to establish alternatives and outcomes, so a good decision can be made

  23. What is the biggest difference between a Decision Support System and an MIS 10 • DSS’s are interactive and ad hoc • DSS’s focus on transforming information into knowledge • MIS’s focus on transforming data into information • All of the above

  24. What is the biggest difference between an MIS and TPS 10 • in a TPS there is no analysis • an MIS focuses on reports • an TPS focuses on updating a database • All of the above

  25. How is the analysis different for a MIS vs. DSS 10 • MIS: Analysis involves computing aggregates • MIS: Analysis involves creating useful charts and graphs • DSS: Connects information with decisions • DSS: Builds scenarios

  26. Some Interesting Applications of Expert Systems • Triage – Medical Diagnosis (Medical Expert System) • User enters symptoms • System makes diagnosis • Doctors collective expertise is captured in the system • Patriot Missile Guidance System • Radar identifies Scud missile • System steers Patriot missile to it intercepts Scud missile • Laws of physics, expert knowledge about missile trajectory is captured in the system • Financial Decision Making – Currency Trading

  27. Expert System Categories Decision Making buy/sell risk/no risk rain/ no rain Trouble Shooting / Diagnosis Hello welcome to Dell; how can I help you? Suddenly an idiot seems like an expert. Selection/Classification Tell me what you see, expert system figures out what it really is... Process Monitoring and Control Robot control, assembly-line control, missile control Design/Configuration Specify what you want, expert system figures out specifically how to do it.
