ABSTRACT
A two-class problem is an example of the application of expected outcome loss. This chapter discusses an example of expected outcome loss — pancreas cancer. A decision-tree model is formulated for a two-class problem (at a single state), where one of the classes is cancer of the pancreas. The chapter describes some of the problem-solving equations and protocols in the care system. The bin probabilities of a histogram are estimated or supplied by nephrologists. An example of the bin probabilities for the class-conditional histogram is shown for the single feature Proteinuria. The MEDIPHOR system was designed to compile a computer-stored drug record for each patient. Each newly prescribed drug is checked for potential interactions with drugs already listed in the patient’s drug profile. The chapter shows often used subsystems and sub-subsystems for emergency medicine or family practice. It discusses classes, subclasses, and sub-subclasses of the subsystem thyroid diseases.
