CHAPTER 9 : ENABLING THE ORGANIZATION - DECISION MAKING

What is artificial intelligence?????

Artificial Intelligence (AI) is a simulates human intelligence such as the ability to reason and learn. An advantages for AI, it can check info on competitor. Four most common categories of AI include :

  Expert System – computerized advisory programs that imitate the reasoning processes of experts in solving difficult problems.
An example of expert system in terms of medical…this basic tasks are carried out by medical expert system which is diagnosis, prognosis, treatment, monitoring. In terms of treatment, the patient or physician could access the system through internet. From here, the user could choose from the choice of patient’s databases or patience disease database. Each database would perform the particular task, either from diagnosis module or prediction module. Then the user will received the feedback through internet so that the treatment can be performed. 



     Neural Network – attempts to emulate the way the human brains works – fuzzy logic – a mathematical method of handling imprecise or subjective information.
An example of neural network which is bank loans….imagine a highly experienced bank manager who must decide which customers will qualify for a loan. His decision is based on a completed application form that contains ten questions. Each question is answered by a number from 1 to 5 ( some responses may be subjective in nature). If we had a large number of loan applications as input, along with the manager’s decision as output, a neural network could be ‘ trained’ on these patterns. The inner workings of the neural network have enough mathematical sophistication to reasonably simulate the expert’s intuition. 



Genetic Algorithm – an artificial intelligent system that mimics the evolutionary, survival-of-the-fittest process to generate increasingly better to solutions to a problem.
 Examples of problems solved by generic algorithm include mirrors designed to funnel sunlight to a solar collector, antennae designed to pick up radio signals in space, and walking methods for computer figures. Many of their solutions have been highly effective, unlike anything a human engineer would have produced, and inscrutable as to how they arrived at that solution. 


  Intelligent Agent – special-purposed knowledge-based information system that accomplishes specific tasks on behalf of its users include multi-agent systems and agent-based modeling.
An example of intelligent agent is used in technology in Travel Reservation Systems…a travel agent, software or human, must not operate on behalf of any single airline or any other similar company, so that it will be able to obtain optimum offers for their clients. Therefore, by definition, the perfect software travel agent will be one owned by a travel agency and will work to obtain optimum packages for its customers.  




The best movie I’ve ever watched!!!!
