Document Summary

Reproduce the performance of human beings who are experts in a particular domain (diagnosis of specific mental disorders) Chapter 7 applying symbolic paradigm: expert systems researchers set out to write computer programs that will, mycin infectious diseases. Took in information from doctors about: expert systems mortgage loan applications and tax advice, decision tree each node on the tree corresponds to a question. Each node symptoms, medical history, and blood tests. Asked for information that it did not have. 600 heuristic rules derived from experts and textbooks. has several branches leading from it. Asking questions cuts down on the space of possibilities: you could make a decision tree by asking a bunch of experts to map out what they would do and make their own decision tree. This could then be used to making a program once translated into programming language. This does make for an interesting program however. It is more interesting when a program creates its own tree.
